A new technology that can increase signal integrity in the presence of paths or distortions. Explain the new method.

It also has an ascending or descending continuum, consisting of discrete steps, and the steps are upwards and downwards. Within the ascending or descending chirp carrier modulation, each has a connected modulation property. The relevant data modulation method will be explained. In addition to this, the carrier pair described in Figure 1.2 The function of generating multiple information carrier waves will be explained. A balanced modulator is used for this purpose. Utilizing a single radio frequency source and the preferred method is an exciting up-chirve and single or multiple subcarriers that are frequency acyls that produce down-chirve modulation. Generate sum and difference frequency components in those instances from the transmit source.

Multiple radio waves with optional balanced modulator (depending on data coherence requirements) It is also possible to add frequency (RF) sources to increase signal measurement resolution.

Data modulation is defined in various ways. Carrier wave pairs have in-phase, anti-phase, or four-phase between carrier waves. data coherence, but multiple carrier bears are Data coherence relationships are formed between different members of the pair to Carriers in several directions can be related.

Importantly, at the receiver, supplementary profile processing is Considering the data modulation arrangement, this is stimulated in priority application number PJ9704. ), the receiver tilt control E I (if an acyl carrier is used) connects the local oscillator to its carrier bear within the specified slope. moving from the frequency midpoint or midpoint offset of the data information or within the carrier.

The prescribed modulation directives also refer to the specification PJ 9704. be understood as "regulatory directives" in priority documents within this specification. I can do that.

Within the scope of the integral detection that is the subject of said claims, related features include The need for end-point reduction or processing end-point measurements that require resolution into be. It is not synchronized, but has a time-of-arrival (TOA) difference from compatible transmissions. All transmissions (vehicles or traceable target) and a set of periodic epochs between receiving members and in a time-based reconstruction method. The number of high-resolution variable measurements required to resolve an epoch within is 1 per epoch period. It can be reduced to Even with such dramatically low sample rates, the ramp control 5 to 10 nanoseconds within a 1 millisecond transmission interval when using a controlled modulation protocol. The time domain decomposition of can be achieved.

The features of the present invention are, in particular, that the absolute position of a moving target can be determined using radio waves or other magnetic or acoustic signals. It can be applied to tracking by radiant energy systems. Its encoding is Can be done with increment or decrement vectors, amplitude, time, frequency, phase or This results in variations in the spacing modulation regions and combinations of such regions.

Improvements in information recovery can be achieved in these areas alone or in combination. , a reference set in the sample interval generated at each receiver, i.e. modulation interval replication. External standards, e.g. atomic clocks or systems, according to standards established from Through time-domain processing as a change with reference to the epoch derived from within itself. It can be converted to distance. The accuracy and resolution of this measurement system are superior to conventional methods. Or use the same scale (with the same number of bits) in terms of Daichimino cleanliness. Larger than existing systems.

The reduced bandwidth and sample rate used in epoch data restoration are the bandwidth or decomposition Can be used without the usual compromises in resolution performance when sacrificing resolution. . Several features coexist in the invention and depend on the nature of the signal information and requirements. ing.

As system complexity increases the demand for high accuracy, later features become more May need to be embedded within high-demand applications. Incremental Generates and transmits specified signals in the decrement time, frequency or amplitude, phase, and interval modulation areas. A transmitter that can control the It is synonymous with ``Go Modulation''.

The defined characteristics (variable rIR) are mathematically definable so that they can be reproduced electronically. Otherwise, each receiver must transmit such modulation before it actually arrives. All receiver systems in the network should be able to understand the characteristics of the received modulation. It should be possible to estimate the In other words, for the receiver, the announcement of the characteristics is required, as indicated by the stimulus or stimulus attributes disclosed later in this specification.

The transmitter must generate modulation conditions before transmitting the slope control modulation profile. The modulation conditions (stimulus or stimulus attributes) are defined by a tendency, here referred to as SCM. It has a unique frequency profile that is not included in slope control modulation.

SCM (Standard Modulation) heralds the display function at each Rx-by. This feature , application number PJ9704. Oh "Improvement of Vehicle Tracking System" application filed on April 20, 1990 in Stralia It is included as a provisional specification of the title and a priority claim within that specification.

important person Diagram 2 will be explained. Diagram 2 depicts a dual carrier pair transmitter. Self The floating continuous array RF source "A" is the balanced TA device "LJrIJJ pair of RF ports. supply. Their source frequencies are denoted as (fc) and the trigger generator “T” The result is (tgfc).

The specified slope generator “■” is changed to the output chirp (f i (de I ta) j). Given to the LO boat of regulator "L". The resulting DSB output from this modulator is It consists of sum and difference kuzuha soft.

(Tgfc) - (fi(deHa)J) and (Tgfc)÷(fi(deHa) )J)''Let this carrier wave bear be (Tgfi).

Similarly, the prescribed slope generator “Q” with output (fg (delta (j)) is , to another balanced modulator "U" to generate a carrier bear.

(Tgfc) - (fq(deHa)D and (Tgfc) + (fq(del ta)D Let this carrier wave bear be (Tg　f　Q).

Therefore, during the period (Tg), the offset is caused by the difference between (fQ) and (fI). We will have a pair of DSB carrier bears (churbs) that are (delta)j is the instantaneous frequency offset.

Let the upper sideband components of (Tgfi) and (Tfgq) be "Up".

The lower sideband component is "Lp".

Next, the two carrier wave pairs are combined by a hybrid combiner rH, and the power amplifier It is amplified by the "PA" and propagated by a suitable antenna.

The prescribed slope generator is described on page 11 of priority application number PJ9704. It consists of a pair of VCOs linearized by local negative feedback.

The effect of such feedback is to control the control port in a VCO with a linear transfer function. This results in relating the output frequency to the output frequency. For this explanation, use voltage control. Please keep this in mind. Alternative implementations using power control are equally valid and applicable.

The chirb voltage (c v q) is applied to the control port of "VCOQ". (c vq) can be expressed by the following formula.

cvq=qq(delta)j+/-oq(QQ) and (oq) are constants , (9q) is the initial frequency offset voltage and (oq) is the gain (or span) It is. The period (delta) j is the prescribed slope function fps (j) at a given moment This is the result. Generally this function is segmented. For example, this is up, It can be composed of down or a series of varying slope segments. They are The specified director associated with the previously defined stimulus attributes disclosed in Application P.J.9704 related to a collection of events.

The same defined slope function is used to feed the "vCoI".

Variable subscripts can be replaced as follows:

cvi=gf　Cdelta＞　j+/−oi Mikokote g　g　i)　(o　i) is , are the gain and offset constants of "vCoI", respectively.

The prescribed slope function for generator rQJ is the same as generator ``1'', but with the initial frequency Offsets are different.

21! to provide coherent carrier detection as described elsewhere herein. There is an integral relationship between fq (j=o) and fi (j=0) (initial frequency).

To clarify, fQ=n (f i), where n is an integer.

The normal prescribed slope function added by IJ rQJVC○ is defined as a "high plane". It is known as This is the main frequency acyl of the modulation system implemented by the system. It is an ingredient. The terms "high plane" and "churve" are synonymous.

The formation of the r-high surface is triggered by the trigger generator TG.

Subchurve or "low plane" data modulation is performed by subchurve generator rscGJ. Added to the "higher plane" prescribed slope.

Diagram 5 shows two pairs of data carriers “Up” generated by the above transmitter. A receiver capable of converting "Lp" is shown.

Stimulus attributes are not shown but are assumed to be present. Stimulation is offset frequency number, coherent data pairs X, y are generated.

The carrier wave is generated by a circuit configuration similar to that in FIG. Heerence is represented by SCM (theta) t and SCM (theta) q. The above The offset is represented by (Voi) (Voq). Regarding Chart 5, frequency conversion The device is rVcOLJ rVc.

Convert "U" accurately. Each of them is a If the relationship is satisfied when the relationship is detected, the specified relationship is maintained.

The chirve detection process is performed by detecting a variance having an inverse variance characteristic with respect to the expected stimulus attributes. It includes a delay line and provides compression receiver functionality. The bandpass filter is shown in Figure As shown in Figure 5, it is shown as two pairs of 30MHz and 40MHz. The data modulation component of the stable IF frequency is passed. Multiplying detectors each have individual It is possible to perform synchronous demodulation of the carrier SCM component using a locally generated reference. The reference has the unique feature that it is not recovered from the input signal as in the prior art for synchronous demodulation. Provide a person in charge.

Instead, the synchronization is done through an alignment processor with the phase of said VC○. A frequency/phase lock acts to establish the relationship between the input carrier bare IF multiplication. This is accomplished by a loop control loop. The above alignment is consistent with multipath distortion. It is established and strengthened by the diversity of differently arranged frequencies. So As a result, the effect on the phase alignment process output from the rFPA in Figure 5 is Majority voting of the phase alignment to establish the limit retention function is allowed.

Data output A! A, B,! B is related to the data phase relationship described in the original transmission. and used to further control future requirements.

A,! A, B,! Note that B is also quadrature rather than an antiphase description.

In other words, A=O! A=+ to 190 degrees.

A more basic receiver operating with a non-offset carrier bare transmitted signal is shown in Figure 4. has been done.

Communication systems may utilize various novel acyl techniques (exemplified herein) to transfer information. In systems where delivery and receiving performance levels are reached and multi-user access is required. Provides the benefits of multiple access. Radio ranging is based on data related carrier waves. Rising and descending changes with continuity that enable epoch reinforcement methods based on phase relationships. Provided by the tonality continuum data arrangement method. Special code for surface or bulk sound The sound is the input that is intercepted in the compolouver or digital correlator. Used to generate arrival time differences between information and reference information (described in this disclosure) . Enhance the integral detection method to decompose epoch detection as described later in this disclosure Due to the superposition of the rectangular waves that generate the triangular product, the interaction of the rectangular waves or the digital recovery Emphasis is placed on issue information. The integral detector was launched in Australia on April 6, 1990. The subject matter of the present disclosure is registered provisional specification P.J.9527 and herein included in the priority claim document.

In the example method, each data packet (the smallest discrete amount of data) It is represented by a subcharb and is the shortest frequency excursion within the main modulation. , ascending or descending triangular steps or any discrete alternative modulation bear, and this implementation The example can represent up to 4 bits of data, and in ideal situations 8 data bits. An m-array vector decision can be generated with a receiver that can represent .

The desired subchirp duration is 10 microseconds or less and should last until the entire SCM is completed. This is the final point where the others follow. A subchirp is a finite data set, A set of apex extrema forming an m-array determined conformation around the Pubea field. The field consists of a subchirp duration interval and a specified modulation within that interval. Becomes a vector. This is illustrated by Example S.

Evidently, the total slope control modulation consists of a series of said subchirp pairs, with each higher plane The final frequency profile of the specified slope controller's dv/dt (slope) and polarity (direction) ). Specify a set of composite profiles for the tilt controller to The complex is caused by a regulated, progressive change in the slope of the higher plane, which is completely independent of the sharp slope set. Collision tolerance can be achieved within a multi-user environment.

a series of said subchirp vectors, each having a linear or digital modulation component; The high-level surface profile modulated by A becomes the modulation vector, and the finite array Belongs to a set. The finite set of sequences can be converted into a single vector by appropriate signal processing functions. into a process parallel to braenfanos, deemfanos, or inverse array compression techniques. Therefore, it is possible to equalize within the time domain so that synchronization can be achieved from any set. This is it The digitized results of either set are normalized to the absolute sample interval points. (renormalization) allows for sample spacing that is a property that can be renormalized. The renormalization function is Moreover, it can be realized by an analog method such as instantaneous frequency correction.

The duration of the subchirp bear or optional subchirp component above is Equal to sample interval. The sample interval (modulation interval replication) is limited subchart Proximity tolerance or the same By choosing equicrystalline frequencies, the modulation spacing produced by all target transmitters Make equal.

High plane frequency profiles are defined for various application specific signal sets. Both sets are determined using the stimulus or stimulus attribute signals described later in this document. Synchronization can be done due to the fact that it can be predicted by the receiver. Ru. This allows the carrier bear subchirp content to be adjusted to the established prescribed slope sample in Table A. closely tracked by the control process defined by the pull and retention techniques summarized in Table A. Rukoto can.

Effectively measures the arrival time of each epoch and the slope of each subchirp (and thus data contained within the subchirp interval). No surface or bulk wave devices (conlouver, correlator or dispersive filter) The digital correlator operations further described are necessary to extract the required information. It is used in parallel processes with matching of each property, which is an essential function. instead Digital profiling can also be used as outlined in the four examples below.

Epoch timing error is a known timing reference for signal ports and reference signals. can be obtained as the integral or superposition of the timing difference between the arrival times of the information, The reference is locked as a sample interval at each receiver. Compol to use Since the server intercepts the signal for the duration of Tx with almost 100% probability , T fired every 27 m at times OTm, 2Tm, 4Tm with a duration of approximately Tm. It has a reference signal of x and an interaction time of 2Tm.

When many users access and use a single service, competition for information due to transmission collisions A problem arises when losses occur. Destructive impact compared to previously used methods It is a system that is mainly suitable for multiple users and has few occurrences of conflicts. To the present invention One distinguishing property provided by the Asynchronous Multiple Access Signaling Protocol is that The collision tolerance is almost 100%.

This method uses analog or digital signals added to multiple carrier waves as described below. It includes several modulation schemes that enable excellent restoration of SCM, which is digital data. I'm here. A precisely defined frequency band is utilized for each carrier bear, but this Bands can be static or dynamic for fixed or acyl frequency methods, respectively. .

The data detection enhancement is such that each bare carrier modulation component is IF carrier pair data modulation component or carrier bear synchronization coherence that causes bare resulting in one or more simultaneous static intermediate frequencies that can maintain Locally transmitted at the same distance or offset from the midpoint of the carrier bear frequency distance demodulation process and rF that can be related by mixing at the Quantity relations fO (for the first IF member) and 2fO (for the second IF member) Achieving this for carrier coherence while actually holding to This can be achieved with a new example.

■, This frequency separation of a ratio of 2 means that the carrier coherence is first as shown in Figure 3. IF passes the integration element E to remove the two-phase modulation and double the carrier frequency. , thereby demodulating the information when passing both carrier waves through an average mixer M. The coherence is restored using the second IF by excluding the phase modulation that enables the This is necessary when necessary for two-phase demodulation (restoring the originality).

Figure 3 depicts the details of the upper chirp set, clearly using the down chirp slope. The lower chirp set process, which is essentially a copy of the upper set, is called the ``lower chirp It is drawn in the expected form (details are hidden) in the box labeled "Set". .

A parallel digital correlator is illustrated driving each demodulated data output. The correlator is a conventional system that serves to program the state machine functions of the device. by expanding to a two-port data input device with dual correlated reference channels. can be combined into one device. The correlator reference code is programmable at top speed and provides code-acyl correlation functionality. Programmer If the data ripple time requirement is met by the Mable reference code chip speed, At least I data clock period comparison times can occur. The above de The ripple time is the m-depth parallel data after correlator (usually coded) sequence. is the number of lock cycles required to arrange the required location within the memory array depth of , the position yields the appropriate result from the n-bit output port.

In the example, the correlated signals are time sequenced so that a high speed parallel shift register can be used. The memory array is implemented using a star.

For special code sequences, the reference or the contents in the memory array have random access that allows such events to occur due to loss of data (bad signal pairs). noise ratio information condition, etc.), based on the n-bit binary output result from the current correlation process. criteria based on the level of confidence that the It is desirable to The code decomposition process consists of the n-bit binary data from the correlator. It is possible to rely on special data replacement based on changes in the output.

This is the more coherent intermediate frequency carrier of the carrier pair or from multiple carrier pairs, such multiple carriers can be arbitrary in a general sense. to choose if one member of the pair suffers from multipath signal distortion. achieved. Multiple voting is then used to determine a satisfactory initial synchronization alignment. and then a strictly defined slope of the frequency profile (high surface profile). Attach it to it. In the method of the embodiment, the control loop is a voltage controlled oscillator (hereinafter v (referred to as CO), with the option to disable from output phase advance/delay control. There is. The vC○ is the correlation peak, phase, or frequency of data modulation. is derived from carrier coherence modulation of a combination of specific carrier pairs.

The Intermediate Frequency (IF) component is essentially a burst signal during the course of a packet. Maintaining the duration, data-related carrier pairs are set to intermediate frequencies between said carrier pairs. or the result mixed with a local oscillator placed at an intermediate offset of the instantaneous center frequency. It is a fruit. This interacts in the manner of the example to yield some property-dependent results. This results in two %IF components that are stable components that can be used. A) Normal Passing through a narrow band filter.

B) If it is 4-phase or 2-phase and processed by a phase-sensitive network, the carrier wave Demodulation of the information contained within the pair.

C) A desirable transmission interval of 1059 seconds or less is determined by Doppler analysis, excluding multiple pairs. This is because Doppler is resistant to the difference between two spaced frequencies. This is because they do not appear at the above-mentioned short intervals except for. This property in spacing Utilization is important and multiple pairs are processed for the associated Doppler properties.

Any number of fixed frequency oscillators when mixed with a specific number of swept oscillators Simple sum and difference relationships for wave frequency (RF) resonators. Continuation of sweep component (SCM set) Mirror image or frequency direction (opposite sensing chirb modulation) in time and span, respectively ) involves selecting a start/stop frequency that produces a reversal of .

When utilizing full acyl deceleration, the system operates in slope-controlled burst mode. Here, frequency agility refers to the frequency or stimulation described above. It is a function of the slope control of the rate of change of the carrier pair frequency that refers to events such as attributes.

For example, the simplest configuration is shown in Figure 5, where the radio frequency oscillator source A is Used as carrier input to double sideband or parallel modulator B, which Two carriers, G and H, each with a frequency acyl slope of 4 MHz achieved in time T wave, which has a burst or packet duration known as SCM.

This relationship will be computationally by making available on-the-fly sum averaging of corresponding points in the The rnJ multiple average value for each cycle's rnJ samples generate. Because of the prescribed slope in the modulation, its values are predictably spaced and brings the benefits described.

(4) Broadband char of much shorter duration than subsequent hybrid char The chirb attribute components are roughly reduced by chirb compression or by detecting the superposition of wideband chirb signals. It works to predict arrival times and allows accurate epoch derivation from hybrid processing. Dual system signal definition follows.

Multiple access to multiple receiver-decoder configurations each triggered by gender recognition It becomes possible to decode multiple messages using this method. Multiple access has two competing methods. This is possible only when an appropriate amount of time has passed between the sages, and this time is generally 20 microseconds or less, and therefore the system for handling 'n' multiple asynchronous messages is The statistical probability is very high. This possibility increases if the packet duration is short.

This type of alpha access is a common frequency band used in parallel, so CDM A standardized format, with a small This results in short range linear CDMA type access with cells. The second shared situation is the main service, there is no risk of data loss due to interfering carriers, and it are generally static and therefore cannot be excluded from the data content of an otherwise continuous carrier. A default SCM profile is created and maintained as a template in each receiver. This makes it possible to track the carrier through high-level interference, and the carrier itself is very low. Due to its low operating output, there is no threat of interference. Data redundancy also This is desirable because it allows very high-speed transmission with array encoding, and multiple voting is one method. qualifies data between subpackets within a message.

As an acyl mirror image carrier pair, the chirb-related carrier can be predicted by the method of the embodiment. Arrange transmit shapes and perform supplementary profile processing to create several multiplexed transmissions. describes a new method that can increase signal integrity in the presence of traffic, noise, or distortion. Ru. This arrangement is a slow chirp carrier frequency profile associated with the preamble. It is a signaling rule in the form of a unique preamble attribute component indicating .

Acquisition profile processing is illustrated in the receiver schematic diagram of Figure 3.4.5 and is illustrated in the example embodiment. The method selectively filters a stable intermediate frequency (IF) with fast chirp results. SCM according to integral detection and dual carrier pair processing techniques to pass data such as Asil receiver local oscillator (LO) or multiple LO prescribed slope generator for messages Consists of a statistical arrangement of components.

In one priority document (PJ 9704) expressly included in this description: From the details, the receiver LO tracks the two carrier components simultaneously and uses a common filter. As you pass through it, you will be able to form pairs with nearly identical results. child , the carrier wave d f/d t is unidirectional (as shown in Fig. 5, they are alternate ), LO is a carrier wave near or in the frequency space between the carrier waves. Track the pair.

It also has an ascending or descending continuum, consisting of discrete steps, and the steps are upwards and downwards. Within the rising or falling chirp carrier modulation, each has a connected modulation property. Belong! - Describe the data modulation method. In addition to this, the carrier pair described in Figure 1.2 The function of generating multiple electric information carrier waves will be explained. A balanced modulator is used for this purpose. Utilizing a single radio frequency source and the preferred method is an exciting up-chirve and single or multiple subcarriers that are frequency acyls that produce down-chirve modulation. Generate sum and difference frequency components in those instances from the transmit source.

Such a multi-image carrier pair is such that said carrier pair receives a majority vote and the resulting Multiple receiver IF circuits with delay equalization and signal processing to extract data modulation excursions When tracked by , it is used to provide multipath compensation.

Data modulation is ordered according to the receiver design of the modulation facility, and carrier pairs are It is possible to have in-phase, anti-phase, or four-phase data coherence between transmit waves, and multiple A carrier pair produces such a data coherence relationship between different members of the pair. , the carrier waves in the same frequency direction are related, and the offset conversion is performed using Control your sexuality.

Importantly, at the receiver, supplementary profile processing is Considering the data modulation arrangement, this is the stimulus in Priority Application No. PJ9704. for another carrier pair tracking (indicated by the preamble written earlier as Receiver slope control (if an acyl carrier is used) allows the local oscillator to be controlled at a specified slope. Move from the frequency midpoint or midpoint offset of that carrier pair within the diagonal and If the data information or phase alignment within the carrier wave is satisfied, it will stick to the fixed arrangement, The array maintains strict adherence to the specified prescribed modulation directives and is invariant for each stimulus or stimulus attribute used within the receiver network of It is a basic or composite profile. Default modulation directives are also defined as "default modulation directives". can be understood as a “directive”, which can be understood as a “directive” and can be understood as a A receiver control parameter that describes the qualitative characteristics of the PJ 9704. , which is expressly incorporated herein.

Within the scope of integral detection, which is the subject of claim document PJ 9527, the relevant features are The need for final or end-of-process measurements where pock resolution is required to a certain degree of accuracy. This is a reduction in the necessity. This results in time-of-arrival (TOA) differences from compatible transmissions. All transmitters (vehicles or trackable targets) in the systemized network ) and the time base reconstruction method (rather than synchronization) between the receiver members, with a set of periods. The number of high-resolution measurements required to resolve epochs within a typical signal is It can be reduced to one. Even with such dramatically low sample rates, the slope 5 to 10 nanoseconds within a 1 ms transmission interval when using a controlled modulation protocol. A time domain decomposition of seconds can be achieved. The features of the invention are particularly Tracking relative position by radio waves or other electromagnetic or acoustic radiated energy systems It can be applied to The encoding can be done with an incrementing or decrementing vector. output, amplitude, pulse position, frequency, phase or interval modulation regions and such regions. This results in a change in the combination of areas.

Improving information recovery can be achieved in any of these areas alone or in combination. can be set to a set standard, i.e. the sample interval generated by each receiver. An external reference, e.g. an atomic clock or system Through time-domain processing as a change with reference to the epoch derived from within itself. It can be converted to distance. The accuracy and resolution of this measurement system are Identical measurements due to tight system tolerances between measurement tools (modulation and sample rate) This is an improvement over traditional methods using a time reference, with integer equality allowing microseconds An amplification error occurs when sampling the rise time of .

The reduced bandwidth and sample rate used in epoch data restoration are the bandwidth or decomposition can be used without the usual performance compromises of resolution. . Several features of the invention coexist and depend on the nature of the signal information and requirements. The most basic of these is the addition of a data carrier within a triangular continuum at a mobile transmitter site. The triangular shape favors linear regression and is similarly suitable for There is a sine modulation that allows any point on an object to be converted into an angular position referenced to 0 degrees. Ru.

of all sample points taken at spatially distributed intervals for compatible repetitive signals. The relationship between exists if the sampling is synchronous, and any sample is Reflect position. Here, the signal slope is specific and four spatially distributed receivers are used. In some cases, each set sample point is reached by a known constant (specific modulation slope). The location is reflected by the arrival time difference. In other words, the epoch was digitized in bolts. and refers to this specified dv/dt result. To rebuild the envelope When using any sampling rate such as oversampling to Signal processing is time consuming and therefore real-time tracking is particularly useful for fast targets. If you do, you will become pregnant. Using harmonically related sampling (with respect to the modulation interval) When the ) - enables real-time tracking for hard-wired receivers. integer repeat sample points The modulation data is accurately maintained by the frequency tolerance of geographically separated matched crystals. The carrier wave IF of each cycle is at the same phase angle.

The scenario is therefore a distributed network of fixed receivers with time-equalized sampling. The result of a randomly generated predefined message is The difference in paths results in a phase-shifted zamble value between receivers.

A more basic technique uses detection level triggers to achieve time-of-arrival extraction.

This is redundant here since any noise present will mask the sensed event at all levels. The mechanism by which the number of discarded levels becomes long and discarded is by the zero-crossing epoch detection method. yielding higher accuracy than possible. Therefore, there is uncertainty in relatively two consistent crystals. By adding , the two matched crystals become negligible within the signal duration of the packet technique. This induces a skew that is

What is important to note is the impact of dense desynchronized transmission on our technique. , in short it is fully cooperative. Regarding the above signalization and sampling, There are further advantages available for asynchronous transmitter fields. i.e. synchronized receiver Within the network, the sample point position is within tolerance and the signal set itself (between modulation The epoch is derived from within the sampling interval and sampling interval).

Additionally, page 5 of PJ 9527 contains at least four asynchronous input messages. A coherent sun that extrapolates epochs from within a spatially distributed coherent measurement of Figure 2 details a pulling receiver network.

This is an example of how the epoch can be derived from the signaling system itself; Astuteness of the crystal element of the sample interval generator at each receiver and each target transmitter The integer sample rate relation to the modulation rate by matching is incremented by the following claim: It will be done.

The ability to function in this way depends on a defined frequency or phase modulated signal from the transmitter. . This returns to its known peak-to-peak value, which is independent of the signal strength and is uncorrelated at the receiver. can be reconstructed from any point of only one sample per modulation interval. The sample relationship is easily regressed to the epoch with the known gap slope of the first transmission. . For limited modulation, the sine relationship for any point in the cycle is gives the corresponding angular position that can have a distance of All sample intervals from now on If the generator is synchronized to an absolute time reference, e.g. the line sign of a local television transmission, Alternatively, the reading of the absolute time reference counter at the time of the sample is It is easy to see that the position calculation of the moving signal can be ensured by carrying the signal.

System complexity has increased the demand for high precision, and the These features may also need to be incorporated into more demanding applications. no increment Generates and transmits specified signals in the decrement time, frequency or amplitude, phase, and interval modulation areas. A transmitter is required, where the signal can be Synonymous with control modulation (SCM) J.

The specified characteristic (modulation) should be mathematically definable so that it can be reproduced electronically. Yes, otherwise such modulation or SCM is transmitted before it actually arrives. It is also possible for all receiver members in the network to estimate the properties of should be. This is possible due to the prescribed nature of all system messages. Then, prediction becomes possible based on the prescribed relationship between preamble stimuli or attribute components.

The guess is made before the modulation actually arrives at each receiver.

This allows the modulation profile to be templated in the receiver electronics after the delay interval is completed. of the stimulus that preserves the modulation profile key so that it can be predicted by Depends on preamble position. In other words, the receiver must display the specified modulation characteristics. is converted into a signal by the stimulus (attribute component).

The transmitter thus generates the modulation conditions before transmitting the slope-controlled modulation profile. The modulation conditions (stimulus or attribute components) are now slope controlled. It has its own frequency or modulation profile that is not included in the modulation.

The SCM (standard modulation) is predicted by the display function in each receiver.

This function was applied in Australia on April 20, 1990 as a vehicle tracking system. As described in the provisional specification application number PJ 9704 entitled “Improvements of a stimulus or stimulus attribute whose contents are expressly included in this specification in their entirety. Ru.

SCM can also be predicted without display capabilities. Epoch or data Instead of extrapolating from a few sampling rate results to a subcarrier rate, the modulation interval repetition and Use averaging for both message repetitions. For repetitive signaling, the template The match is based on the receiver specified directive criteria and the incremental delay of the input signal or the transmitter. A time-normalized reference signal between devices serving to extract epoch or position information. When the signal persists in the surface acoustic wave compolouver, which is prepared as a matching filter along with the This can be achieved by convolution between. Attribute independence is based on predefined signal modulation and Specified burst duration, repetition rate, and sequence in multi-transmitter positioning systems ・Achievable due to pattern recognition.

Table A Diagram 2.3.4.5 will be explained. Diagram 2 shows a dual carrier pair transmitter. is depicted. A free-running continuous RF source “A” is connected to a pair of balanced modulators “L” and “U”. Provides an RF port for the Their source wave numbers are denoted as (fc) and are gated by generator "T" and the result is (tgfc).

The output chirp (fi(delta)j) from the prescribed slope generator "IJ" is the modulator " It is given to the L○ port of "L". The resulting DSB output from this modulator is the sum and It consists of difference frequencies.

(Tgfc) - (fi (delta) j) and (Tgfc) + (fi (d elta) i) Let this carrier wave pair be (Tgfi).

Similarly, a prescribed slope generator r Q J with output (fg (delta (j)) is applied to another balanced modulator "U" to generate a carrier bear.

(Tgfc) - (fq (delta) D and (Tgfc) + (fq (delta) lta)j) Let this carrier wave bear be (Tgfq).

Therefore, during the period (Tg), it is offset by the difference between (fQ) and (fI). It will have a pair of DSB carrier pairs (chirbs). (delta)j is , is the instantaneous frequency offset. Upper sideband components of (Tgfi) and (Tfgq) Let rUl)J. The lower sideband component is “LpJ.

Next, the two carrier waves are combined by a hybrid combiner "H", and the power amplifier rPA' and propagated by a suitable antenna.

The prescribed slope generator is described on page 11 of priority application number PJ9704. It consists of a pair of vCOs linearized by local negative feedback.

The effect of such feedback is to control the control port in a VCO with a linear transfer function. This results in relating the output frequency to the output frequency. For this explanation, use voltage control. Please keep this in mind. Alternative implementations using power control are equally valid and applicable.

The chirb voltage (cvq) is applied to the control port of "vCOQ". (c v q) can be expressed by the following formula.

CVQ=QQ (de l ta) j+/-oq (q q) and (o q) are constants where (Oq) is the initial frequency offset voltage and (oq) is the gain (or span). ). The period (d e 1 t a) j is the prescribed slope function fp at a given moment s(D). Generally this function is segmented. For example, this is the result of It can consist of up, down, or a series of varying slope segments. those The prescribed directories associated with the predefined stimulus attributes disclosed in application PJ9704 related to a set of tives.

The same defined slope function is used to feed rVco rJ.

Variable subscripts can be replaced as follows:

cvi=gi (delta) j+/oi where (g i) (o i) is rVcOI'' gain and offset constants, respectively.

The prescribed slope function for generator rQJ is the same as generator "I", but with the initial frequency Offsets are different.

To perform coherent carrier detection as described elsewhere in this specification, typically f There is an integral relationship between q (j=o) and f i (j=o) (initial frequency).

To clarify, fq=n (f i), where n is an integer.

The prescribed slope function added in “■” and rQJVCO and common to them is “High Known as Face J. This is the main frequency of the modulation system implemented by the system. It has several acyl components. The terms "high plane" and "churve" are synonymous.

Filming of the "high plane" is triggered by a trigger generator "TG".

Subchurb or “low plane” (this is synonymous with “fast chirp”) modulation is added to the ``high surface'' defined slope by the subcharb generator ``SCG''.

Diagram 5 shows two pairs of data carriers rU, p generated by the above transmitter. A receiver is shown that can convert "I'Lp". Stimulus attributes not shown However, we assume that it exists. SCM is offset frequency coherent data The data modulation phase generated by the pair X, y and between another carrier bear rUpJ rLpJ bring about relationships.

Regarding Chart 5, frequency conversion The device accurately converts r¥cOL” [VCOU”. Each of them is a bird generator If "TG" is satisfied with reliable chirp detection, the specified relationship is maintained.

The chirve detection process is performed by detecting a variance having an inverse variance characteristic with respect to the expected stimulus attributes. Contains a delay line and provides compression receiver functionality. The bandpass filter is shown in Figure 5. Stable IF shown as two bears at 30MHz and 40MHz as shown in Pass the data modulation component of the frequency. Multiplying detectors each have an individual carrier SC Synchronous demodulation of the M components can be performed with a locally generated reference, said reference being synchronous It also has a unique relationship in that it is not recovered from the input signal like conventional techniques for modulation. Tarasu. Instead, synchronization is performed through the alignment processor frequency/which acts to establish the relationship between the phase of the input carrier pair IF multiplication Achieved by a phase-locked control loop.

A more basic receiver operating with a single carrier pair SCM transmit signal is shown in Figure 4. It is assumed that the stimulus attribute exists. Baer's synchronous acyl sidewave detector is L○ and near-DC components are generated for cost-effective virtual reality tracking, tools or robots. Requires data or identification modulation such as spot positioning, difficult alignment, etc. A single The flexibility of locally generated LO3CM signaling is demonstrated.

The 8MHz IF bandpass filter uses sideband epoch detectors to detect amplitude and frequency errors. – forward/delayed epoch error signals that serve to track RF carrier nonlinearities. Temporary knitting can be advantageously performed to accommodate roll-off versus band width. figure The epoch detection system as described for Table 5 and others in the example are , a novel rmJ-A, which increases data density without significantly increasing signal bandwidth. It has a ray-coded data function and can use multiple carrier bears for multipath compensation. It is particularly efficient when a given data modulation sequence between bears is Provides simplification of epoch detection and data density by combining m-array states. results in an increase in

Within a message, radio ranging is improved by the way data is arranged between carrier bears. The ascending or descending modulation continuum (basic built-in chirb modulation) is tracked within the receiver. After being detected, the IF ratio output is stable and the data is first aligned, i.e. measurable. resulting in offsets due to multiple paths. The subsequent compensation is that the multipath is Based on the propagation theory that the receiver changes the acyl carrier with an indirect path. The propagation delay varies with frequency and the image delay for the direct path signal The length also changes. The data arrangement may vary depending on the design within the receiver electronics. where the performance depends on the synergy between the design and the relationship between the data carriers; Some examples will be explained below.

Decisions specifying specific carrier-to-carrier relationships are based on system range, hypothetical errors, and data rates. As long as all requirements reflect receiver complexity for a given CDMA performance, It goes with the application. A schematic example (for which, within the general spirit of this disclosure) (There are many examples), there are two scenarios, but it is necessary to repeatedly modify and elaborate. is necessary, and will be briefly described here without data inference. Explanation regarding Figure 1.2 As explained, to mirror the applied modulation between frequency offset images, Generation of multiple images of Asil Message. For devices with the purpose illustrated in Figure 3.4.5. The phase aligner or sideband detector detects the majority of the phase agreement between the carriers. Then you will have the opportunity to decompose the phase relationship of the predefined carrier bare data. Significant improvements in position calculations by compensating for temporal associations I can do it. Majority consensus is based on maintenance or adaptive inertia against recurrent events. satisfied by sufficient confidence reflected by statistically related agreement indicating confidence. Ru. Inertia can be exploited in phase aligners to integrate multiple functions such as inertial delay-locked loops. According to the integral detection principle (P J 9527) resulting in a homing device The majority epoch position is a set inertial level. Increment or decrement in time by an amount of adaptation inversely proportional to each subsequent sample close to the mean value be done.

In this arrangement, the subchaves or symbol spacing is the phase or frequency Consisting of several encodings, less than three orders of magnitude longer than the required resolution duration, which significantly reduces the data modulation bandwidth. repeating array between symbols is a system that requires timing accuracy to achieve a given system resolution. maximize the intercept probability of the analog implementation of the analog implementation of the counterpart. The frequency linearity requirements for the application become simple. The integral detector was opened on April 6, 1990. PJ 9527 of provisional specification registered in Stralia is the subject of this disclosure. , incorporated herein in its entirety.

In the example method, each epoch or analog implementation of the data transmitter is The data packet (the smallest discrete amount of data) is the shortest frequency excursion within high speed modulation. Cursion rising or falling triangular steps or any discrete alternative modulation bear In this example, up to 6 bits of data can be represented. more complex modulation combinations can represent 12 data bits. m radio vector decisions can be generated at the receiver. This is m-array signaling For each data modulation interval, there are m squared combinations of carrier waves for each data modulation interval. It is utilized by the data relationship between the carrier pair. This fast chirp duration is preferably less than lo microseconds for the RF multiplied signal, in which case the gold SCM is completed. A continuum of connected fast chirps continues until , a pair of apairs forming an m radio-determining array around the subcharb pair field. The field consists of the fast chirp duration interval and within that interval. becomes the specified modulation vector. This is illustrated by Example S. This example is just an example of any profile and at least one other carrier. Data density can be increased in preferential association with modulation.

Evidently, the full slope control modulation consists of a series of said subchurb pairs, with each higher plane The final frequency profile of the specified slope controller's dv/dt (slope) and polarity (direction) ). A set of composite profiles is defined for the slope controller to provide high speed Hybrid modulation with high or low chirp completely independent of the chirp set Collision tolerance in multi-occupancy environments through regulated gradual changes in the slope of high-level surfaces in range can be achieved. High-level profiles can be linear or digital, respectively. has a modulation component, is the modulation vector, and is a set of the modulation vectors belonging to a finite array set. Modulate with subcharb pairs. The finite set of arrays can be processed by appropriate signal processing functions. , single vector reinforcement, de-emphasis or inverse array compression method can be equalized in the time domain so that it can be synthesized from any set by a process parallel to It has the property of An example of this would be an l chip in an rmJ-array array. r (decoded into 71J bins, each with words of rsJ depth as addressable strings) and rsJ is the integer number of samples (modulation interval) in each chip. There is an improvement in the resolution of Each address is the sentence between the rmJ bins in the order of symbol encounter. Refers to rsJ values arranged in a string, similar symbol cycles are stacked together and their Allows recursive sample position summation for symbols on-the-fly, symbol counters The center allows a final phase-average for each rmJ bin. Each bottle is It has only one string of rsJ words and a counter.

This ensures that the sample interval is the absolute sample interval point for any digital result in the set. This means that it can be referenced (renormalized). The normalization function is the sum-average The bin string of sample points obtained is taken as a single modulation interval repertoire, and herein Applying the principles outlined in page 2 (7) of , resulting in a single point per bin, yields (8) for one epoch.

Equality performance means that if you can decode each vector and obtain the value of any point, you can Analog methods such as correcting the position of the m-array set to the reference by manipulating the conversion table It is possible.

A more basic example of the analog correction described above is that the comparator has one built-in chirp. It is a form of instantaneous frequency correction in a phase-locked loop with carrier TF and LPF (low-pass filter) output is summed at the reference modulation interval slope before being added to It will be done. The inclined part is constructed with high precision using attribute stimulation and phase alignment algorithm. The time is measured and triggered from the time adjusted to the specified time. The reference slope is within the IF carrier. Advance/delay control is required to enable synchronization with data modulation, and will be developed in the future. Multiple path decisions made by cVo drive analysis between related image carriers within the image enable voting. The rmJ-array state when used with the VcO drive mentioned above. Performs the function of decoding. Multiple slopes can be added without further affecting the multipaths of the epoch results. If you have a long vote, you can sample from the rst part based on the epoch. Ru.

Furthermore, PJ 9527 Page 12 shows the digital data whose sampling rate is time related to the specified transmit modulation rate. details the relationship to the encoded receive envelope. This includes the carrier IF relationship. , in which case subsequent sample points have two points reflected at the required final freshness. Successive intervals within a defined interval relationship that have a slope that results in a least significant bit (LSB) difference or more. It is intended to enter the integer space cycle. This is system compatible realizes the existence of a bull carrier and yields meaningful data that can be correlated with other receivers It's for a reason.

The combined method (data and IF related sampling) smooths out the moving trends at the sample points. It can be used for equalization. Movement trends to form distinguishable results Reflecting the precision amplification of two closely spaced high frequency sources beating together, 1 If one is the standard (sampling rate), the others depend on the degree of phase lead or delay. Can be measured accurately. Within the IF measurement capability, two close frequencies (constant modulation The degree of phase lead or delay in comparing and since the frequency is known, the accuracy of the Doppler shift with one displacement It is possible to achieve a good estimate or average to estimate such trends.

High-order frequency profiles are defined for various application specific signal sets. Both sets are determined using the stimulus or stimulus attribute signals described later in this document. Rough synchronization (arrival time) can be performed in real time with an accuracy of approximately 100 nanoseconds. This is it The contents of the carrier pair and subcharb are related to receiver operation (supported in Figure 3.4.5). can be closely tracked with much greater precision due to the control process revealed in the I can do it. This is primarily due to the fact that the carrier pair modulation relationship is a mirror image of itself. Mirror of a single (or tracking dual) precision high frequency generator frequency converted to the desired RF band By being a statue. This property can be used in the receiver phase or frequency aligner to improve image quality. The carrier wave is generated by leaving only the propagation path error through the diversity measurement of the carrier wave pair. Find the first exact modulation used to create the data, but the first phase of the data modulation They are semi-coherent between the carrier pair and can be distinguished because of their frequency preservation. is multiplied by Details will be posted a few pages ago.

When many users access and use a single service, information is lost due to competition due to transmission collisions. A problem arises when losses occur. The following is destructive compared to the previously used method This system is primarily designed to accommodate multiple users, with fewer conflicts occurring. Book One distinguishing feature provided by the invention is the asynchronous multiple access signaling protocol. The collision tolerance within the vehicle is approximately 100%.

This method uses analog or digital signals added to multiple carrier waves as described below. It includes several modulation schemes that enable excellent restoration of SCM, which is digital data. I'm here. A precisely defined frequency band is utilized for each carrier pair, but this Bands can be static or dynamic for fixed or acyl frequency methods, respectively. .

The enhancement of data detection is that during the demodulation process, the carrier modulation components of each pair are IF carrier wave pair, data modulation component or carrier wave pair that generates a transmission wave or carrier wave pair one or more simultaneous static intermediates that can maintain coherence synchronously Equidistant or off from the midpoint of the carrier pair frequency distance to yield the frequency The field can be related by mixing at the local oscillator frequency in the set. and the IF quantity relations fO (for the first IF member) and 2fO (for the second IF member). (for the IF members of This can be achieved by a new example of achieving this.

This frequency separation in the ratio l:2 makes the carrier coherence as shown in Figure 3. An IF of 1 removes the two-phase modulation and adds an integration element E to double the carrier frequency. and thereby information recovery when passing both said carriers through a balanced mixer M. The coherence is restored in the second IF by excluding the phase modulation that enables the modulation (frequency, etc.). This is necessary when necessary for two-phase demodulation (recovering polarity).

The lower chirb aggregation process, which is essentially a copy of the upper aggregation, is called the “lower chirb It is drawn in the expected form (details are hidden) in the box labeled "Set". . A parallel digital correlator operating each demodulated data output is illustrated. ing. The correlator typically serves to program the device with state machine functions. or to expand to a two-port data input device with dual correlated reference channels. Therefore, they can be combined into one device. The correlator reference code is given Programmable at chip speed and provides code-acyl correlation functionality.

Programmable reference code chip speed ensures data ripple time requirements are met. If the . The data ripple time is calculated by coding an m-deep parallel data word (usually coded) sequence. The locking period required to align the relator to the required position within the memory array depth where the position yields the appropriate result from the n-bit output port.

In the example, the correlated signals are time sequenced so that a high speed parallel shift register can be used. The memory array is implemented using a star.

For special code sequences, the reference or the contents in the memory array have random access that allows such events to occur due to loss of data (bad signal pairs). noise ratio information condition, etc.), based on the n-bit binary output result from the current correlation process. criteria based on the level of confidence that the It is desirable to The code decomposition process consists of n-bit binary data from the correlator.
