Description

Split Codes Multiple Contact Points Communication System Full Description Background of the Invention The present invention generally relates to a Coded Multiple Contact Points Communication System

fragmented (CDMA) This system is also known as a communication system operating on Spread Spectrum 0, to be precise; In particular, the present invention relates to a system and method for providing large capacity and this system (CDMA) provides several simultaneous carrier channels to one or more users in of one within a certain SLY frequency so as to allow the assignment of a carrier channel rate (for messages). dynamically

At a time when multi-path interference is not allowed. It has proven to provide wired and wireless services to groups of users in remote remote locations; 0 "such as those who use telephone systems in rural areas and in various developing countries; it is considered a difficult challenge in recent times. However, these needs have been partially met by wireless services Jie Fixed Frequency Fragmented Multiplexing (FDM) or Frequency-divided multiplexing (FDMA) Cross-sectional Cad multiplexing (TDM) Time-segmented multiplexing (TDMA) ¢ and time-segmented vo systems (FDMA) FD/TDMA), and terrestrial mobile wireless systems. and shortcomings; modern technical methods and methods have been used by Spread Spectrum Modulation techniques (i.e. Spread Cade) to provide instantaneous 00 simultaneous connection to a large number of users; Spread Spectrum Modulation (Spread Spectrum) modulation refers to YYYYV modulation

a signal of information with an extended code signal (diffusion code); The extended code (spread code) signal is generated by a code generator so that the time period of the extended code (Te) is essentially less than the time it takes to transmit a very small part of the information or the symbolic signal; The token may include the carrier frequency of the "message" on which the information was transmitted; This frequency is called the hopper-shaped frequency spread; Lu may modify the signal directly by multiplying the propagating code with the information data signal; In this case, it is called direct succession (DS). Modulation of the spread spectrum (spread spectrum) results in the production of a signal with a broadband that is essentially greater than the band needed to carry the information signal or the information-carrying signal. Simultaneous reception and no signal propagation at the receiver restores 0 of the original information. lea uses demodulation in the receiver reference signal to synchronize in non-spread circuits to the input spread spectrum (spread spectrum) signal which is modulated so as to recover carrier signals and information signals and the reference signal can be spread code (spread code) not Include it with an information flag. The use of synchronous, non-modulated spread spectrum used in wireless communication 1 is described in US Patent No. 0178058 “System and Method for Synchronous Propagation Spectrum Communications” filed by Donald L. Schilling and provides the modulation of spread spectrum (spectrum Spread) in wireless networks has many advantages since many users may use the same frequency band with very little interference between one user's receiver and another user's receiver and the inclusion of extended spectrum (spread spectrum) also leads to + reducing the effects of other interference sources. In addition, methods and techniques for including and de-embedding synchronous propagation spectrum and methods and techniques may be extended by providing multiple message channels for the signal user, each of which is propagated by a different propagation universe, while only one reference signal is transmitted to the user; \VYY

- os Description of the inclusion of such use of multiple message channels by means of a set of synchronous propagation codes that coincide with the radio communication propagation guide spread code in US Patent 1190 (© 1190) entitled Capacitive Spread Spectrum Channel high; Which was submitted and deposited in the name of "Donald L. Schilling" and among the areas in which the extended spectrum (spread spectrum) is used is the area used in the field of mobile cellular communication (i.e. 0 this Jia and cell-powered (PCS) mobile) in order to provide services for personal communication systems and in a desirable manner with the support of a large number of users; Doppler shift control and delivery of high-speed digital data signals with 0 and very low error rates. Such systems use a combination of orthogonal and semi-orthogonal propagation codes; With a sequence of codecs for a pervasive guidebook that coincides with the codec. Each 0 user defines and assigns one propagation code as a function of the propagation function. Among the problems related to such a system; support a large number of users and provide them with orthogonal code; Trading diminishing energy, which is the energy that is available to remote units, and trading the fading effects of multiple paths. Solutions to such problems include the use of multi-phase antennas (that is, they have a group of phases) to generate multiple steerable rays; And the use of very long orthogonal (0) code sequences and very long semi-orthogonal ones. These sequences may be reused by circularly shifting the synchronized code with the central reference; With merging or unifying a variety of multi-path signals. Such problems that are associated with spread spectrum communications and methods for increasing the capacity of multiple connection points are described; Spread Spectrum System (Spread Spectrum) in US Patent No. 49017097 entitled “Spread Spectrum Operated Multiple Contact Point System Using Satellites and Terrestrial Repeaters” filed and filed under the name of Gilheusen et al. The problems associated with previous patent systems focused on or around a reliable future and circles other than \VYY

dd - the receiver synchronization diffusivity depends on it with respect to the signal being received. The presence of multipath fading introduces a problem specific to spread spectrum receivers in that the receiver must track the multipath components to maintain full code phase for the non-spread receiver means with the input signal; In general; Previous patent 0 receivers only track signals of one or two of the multiple paths; However, this method is unacceptable or insufficient because a combined set of low-power multipath signal components may actually consist of considerably more power than one or two of the more powerful multipath components, and the receivers of the foregoing invention track and combine the more powerful components to maintain Predetermined BER 0 _ for the receiver; Such a receiver is described in US Patent No. 50004790, “Diversified Receiver in a Cellular Telephone (Cell) Code Divided Multiple Point Communication (CDMA) Communication System” filed and filed as “Gellheusen et al..” However, any receiver that unifies and integrates all the components of the multiple paths, it is able to maintain a very low error rate (BER) with a signal strength that is less than the strength of the systems of the previous invention because the greater the signal strength is available and available to the receiver (i.e. to the receiver).Therefore, there is an urgent need for a communication system of spread spectrum communication systems (spread spectrum) that uses a receiver or a receiver that basically tracks all the components of the multipath signal, so that with it all the signals of the paths can be integrated and unified In the future, the transmission power required to transmit signals at a given rate can be reduced by negligible error rates (BER). necessary to move users into the system; As long as the power available to users may be limited power. Another problem is associated with what it takes to control and control YYYY

- - Energy in spread spectrum systems (spread spectrum) as it relates to the inherent properties of spread spectrum systems (spread spectrum) in which the signal of one signal user (spread spectrum) can be received by another user receiver in the form of noise with a certain energy level and thus 0 High signal power levels for transmitting users may interfere with the reception of others and also if a user moves from his/her geographic location a certain movement relative to another user's geographic location then the fading and fading of the signal requires that both users adjust their transmission power level to maintain the specific quality and quality of the signal At the same time, the system must maintain the power that the base station receives from all users so that this power remains relatively small. In the end; Since it is possible for a spread spectrum system to have many 0 more remote users than it can support simultaneously; The power control system must then also use a capacity control method that excludes any additional users when the system's maximum power level is reached. Early spread spectrum systems used a base station that measured the signal being received and sent an automatic power control (APC) signal to remote users. Vo and these remote users have a bus with an Automatic Gain Control (AGC) circuit that responds to an Automatic Power Control (APC) signal and in such systems ¢ the base station monitors the power of the whole system as a whole or monitors the power being received from each user; It positions the Automatic Power Control (APC) signal accordingly. The system and method for control and control of spread spectrum power (Spread Spectrum) is described in US Patent No. 0799777 titled “© Control of Power Adaptive to Spread Spectrum Communication Method and System” filed and filed with Donald L. Schilling". This open circuit can be optimized by the user far from the base station; transmitting the automatic power control (APC) signal back to the YYYY station

1 - The rule to influence the method of controlling closed circuit energy. Such control of encapsulated circuit power is described for example in US Patent No. 0017775 entitled “Automatic Gain Control Circuit for a High Dynamic Range Encapsulated Circuit” filed as Charles A. Wilter, TIL et al

8 and A anyway; These systems of power control and control systems show several drawbacks and disadvantages. First, the base station must implement complex power control algorithms; With the increase in the amount or amount of processing in the base station. Secondly, the system actually experiences several different types of energy change, including: the change in the noise energy that occurs due to the change in the number of users and because of the changes that occur in the energy of the signal being transmitted

0 its reception of the specially designated carrier channel; Jie brings about these changes at a different frequency; Therefore, it is possible to make simple energy control algorithms (calculations) in an ideal (typical) form, to display only one of the two types of change (aforementioned). In the end; tend logarithms

Energy (or energy arithmetic operations) lead the energy of the whole system as a whole to a higher level Das and thus; There will be an urgent need for a way to control the power of the spread spectrum (0) that responds quickly to changes in the power levels of the Jalal channel) while at the same time making the necessary adjustments to each power that all users take in response to changes in the number of users. There will also be a great need for a modified spread spectrum communication system that uses a closed circuit power control system that minimizes the power requirements of the whole system while at the same time maintaining an acceptable error rate. ultra slim with singles long receivers; in addition to; The like this f

M - The system will control and control the level of the initial transmission power of the remote user and also control and control the total capacity of the system. It is desirable that spread spectrum (spread spectrum) communication systems support a large number of users and each system has at least one communication channel. In addition to m; Such a system would provide multiple public and comprehensive information channels to broadcast information to all users and to enable those users to make progress in approaching and accessing the system. Using the spread spectrum systems of the foregoing invention this can be implemented by generating a very large number of spread code sequences. Furthermore; Spread spectrum systems will use sequences that are orthogonal or nearly orthogonal to reduce the chances that the receiver will lock in phase or the wrong spread_code sequence; The use and benefits of such orthogonal codes are described in US Patent No. 94 (©) entitled “System and Method for Generating and Reproducing Signal Waveforms in a Code Divided Multiple Point Communication (CDMA) System Using Cellular Telephone” filed and filed as Gilheusen et al. and also in US Patent 0164 entitled “Method and Apparatus for Producing and Generating Hyperorthogonal Conventional Codes and Encrypting These 1 Codes” filed and filed under the name of “Androje. Viterbi". In any case, the generation of such groups of code sequences with such properties is difficult. The generation and production of large code groups requires the generation and production of sequences that have a long period of time before the replay takes place. Therefore, the time it takes for the receiver (device reception) to achieve synchronization with such a sequence will increase. Often, propagation code generators of the foregoing invention combine shorter and shorter sequences and unify them to make more Yoh sequences, but such longer sequences may not be perfectly orthogonal. Hence, it will be There is an urgent need for a modified (improved) method to reliably generate large blocks of code sequences with YVYY

CL

which show characteristic properties that are nearly orthogonal and have a long period of time before re-establishment; However, it also includes the benefit of a short codec sequence that reduces the time required to achieve and lock the receiver to the correct codec phase. In addition, the code generation method must allow the generation of codes of any length of time, as long as the time period of the spread code is often determined by the parameters that are used, such as the data rate or the size of the structure. It is desirable that the transition of the value of user data occurs at a value of the transition of the code sequence. Since the data is, it is usual to require such (oY) typically with a period of time divided by the parameter The property is that the code sequence is of length a multiple of the parameter (1) In any case, the code generators and as is It is known from previous inventions that generally use (¥) that generates and produces codes along linear feedback change registers (LFSR) and some generators include a specific method by increasing the generated code sequence by entering a value of (1-" 5778054). Additional code; as described for example in US Patent No. 100 entitled “Power Supply of a Two-Length Pseudo-Noise Cascade Generator with Rapid Offset Adjustment” filed and filed under the name of 'Timothy Reuth et al.'. And therefore ; The spread spectrum communication system yo 0 will also generate a spread code sequence of even length and at the end; A spread spectrum communication system must be able to accommodate a lot of voice band data; and Services Digital Network (FAX) various data types such as fax in addition to normal streaming voice calls and to increase the number of users integrated (ISDN) include Jie code supported; Many systems use technical methods and methods in coding v. This is to achieve compression of the digital telephone signal; on any adaptive differential pulse (ADPCM) and integrated services digital network; And the other data is that (FAX) is a case; Both faxes are required

Parameters of rapid acquisition (or notching) of long and short codes: The rapid acquisition of the correct code phase achieved by the spread spectrum receiver is modified and improved by designing propagation codes which are as fast as possible to be detected and identified.The present embodiment of the invention includes a novel method for generating code sequences having rapid acquisition properties by using one or more of the following methods; 1 The first is that it may be possible to construct a long code from two or more short codes. The new implementation routines use a lot of multiple code sequences. where one or more of them are acquisition sequences of length (1) with an average attainment or acquisition phase of (21) (r=log) and sequences of this kind having such properties are known (Tan) to those skilled and experienced in The domain of the invention, the mean number of phases of the acquisition test for the resulting long cascade are multiples of (r=log (21) better than half the number of phases of the long cascade. \VYY

The code generators in the ideal form of the present invention take a particular form to generate either international codes; or specific codes. The international codes are Code Divided Multiple Access Point 0 (CDMA) codes that can be received or transmitted by all users of the system. Defined codes are code segmented Multiple Access Point (CDMA) codes that can be positioned specifically to favor a particular connection. And when a group of sequences is generated from the same generator as previously described; Only the seeds of the linear feedback recorder (LFSR) which has thirty-six (71 steps) special Le gi selection are selected in order to generate a set (family) of sequences. Sequences for all international codes are generated using the same feedback recorder (LFSR)Aha circuit.

The method, Cada, tracks the code phase of the © signal. The first is the tracking circuit of the previous invention (preliminary) that simplifies the propagation code phase with the largest value of the output signal for detection and identification; The second method is a tracking circuit that tracks the mean value of the code phase of the multipath signal group and the third method is a center tracking circuit that tracks the typical least square mean code phase of the multipath signal components. The following are described by the calculations (algorithms) by which the propagation code of the multiple connection point signal is traced to the segmented codes (CDMA).

The correction is done using the channel response estimates computed in the pilot tracer signal-powered adapter vector coupling. The filter output signal is a combination of multiple path components that combine to produce a high value. This standardization corrects multipath signal reception noise. The various message aggregation circuits operate based on a unified multipath component signal from the compatible filter. a

In which the subscriber unit has a channel with the wireless carrier station, the normal search is performed by the wireless carrier station to acquire the access points channel. The normal method begins by searching for the corresponding code phases of the long potential impedance and the search is gradually modified to the code phases with the lowest possible impedance. However, after the initial acquisition, the subscriber unit can calculate the impedance between the Jalal wireless station and the subscriber unit by measuring the time difference between sending a message with

International reference guide the receiver as an indication of temporal time. The subscriber unit can receive the impedance value by the wireless carrier station calculating the circular motion impedance difference from above © phase code between the international pilot code generated in the wireless carrier station and the specified received pilot sequence from the subscriber unit; Then the subscriber saa sends the value to the predefined control sl. when the circular motion impedance is recognized by the subscriber unit; get up

That unit modulates the code phase of the internally generated specific pilot and propagated code sequences by adding the required impedance until the subscriber unit of the wireless carrier station appears to be at a fixed, predetermined distance from the wireless carrier station. Although the method of greatest impedance is explained, a corresponding impedance can be used for any predetermined position in the system.

° The method of reducing re-acquisition time by default positioning has the second advantage of saving energy in the subscriber unit. Noting that the subscriber unit that is not powered on or in sleep off mode needs to run the carrier channel acquisition process with low transmission power and increase the power until the wireless carrier station can receive its signal so that the interference with other users is minimized. Whereas, the reacquisition time is successive short and that

- Because the subscriber unit is placed in a relatively fixed position relative to the wireless carrier station, the subscriber unit can increase transmission power in a faster way because the subscriber unit will wait for a short period of time before increasing transmission power. The subscriber unit corresponds for a short period of time within a small error rate when playing back a response from the wireless carrier station if the subscriber unit signal is acquired.

The modem controller (07;1) using signals ... 084 1 082 to facilitate assembly by Adee; the auxiliary adapter vector coupling (1777) emits a noise signal in a reciprocal relationship ARDSPRRST where quantum estimations are computed by the quantum evaluator 0 (1777) It also gives a measurement of the noise level to 800 and the logical sequence (1701) shown in (VV) JS and the modem controller shown in Figure (VY) and each spread signal is entered for the co-channel with the received message (TRO, TRI, TR2, TR3) to the Viterbi symmetric AVIY decoder (VALID 1716 AVY) shown in Figure (VY) leading to forward error correction in the encoded data by approximately 1 bypass. The decoders in the ideal model have a bound length of 16-7 with a ratio of R=12. Uncoded bulk message channel signals are transmitted from the device modem to the highway pulse code modulation (01) (VY) through the modem output interface. The operation of the modem output interface is similar to that of the input modem receiver of the carrier segment ( 100) Shown in Fig. (V7) except in Ala return. Y. The receiving sector of the system modem (VFL Y) performs sae different computations through several phases of acquisition, follow-up, and aggregation of the emitted system message signal from the future.

111 - = When the received signal is temporarily lost (or reduced in a linear manner), the ideal code entry calculations enter the perfect codes instead of the lost or scanty received message data, to prevent the user from hearing loud noises during AS telephony, and the perfect codes are sent to the surface The modem output interface (1717) shown in Figure Yar (VV) of the exit signal emitted by SL 0 the unencrypted message after it has been left by Viterbi decoders (1719 40 no AVIS 7 ) and the special ideal codes are programmed each channel assigned to the telephone by the modem controller (VF) by writing the appropriate word TOLE on the modem output interface a in the current form consisting of “a bit of a stream consisting of TE kbps and a word consisting of bits for a stream consisting of YY 0 kbps 0 Modem-specific calculations for acquisition and follow-up of the receiver pilot signal: The acquisition and follow-up calculations are responded by the receiver to determine the approximate code phase of the received signal and to adjust the synchronization of the modem's receiver collectors With the guideline reference entered and the future guideline follow-up. Referring to Figures (VF) and (71), the calculations are performed by the modem controller (VEY) ve which emits timing set signals to the code generator (£) and those signals make the code generator for the collectors set set sequences Code generated internally according to the measured VV output values and the quantum values emitted by the quantifiers (77711b). The orthogonal channels are from the AUX (1707) coupling vector output values shown in Figure (VY). ) The receiver synchronization setting with the received signal is separated into two phases... Acquisition phase © - initial and sequential phase. Initial acquisition is achieved by cascading the chip code register of the internally generated pilot at a rate higher or lower than the chip code rate of the signal YVYY

YA - - receiver. Initial acquisition is also achieved by dissipating the internally generated pilot chip code sequence and performing a sequence probability ratio check on the output of the pilot binding tool (1711). coming.

0 The subscriber unit's cold acquisition calculations are used by the subscriber unit's system modem when it is turned on and therefore has no knowledge of the correct pilot chip code phase or when the subscriber unit attempts to re-synchronize with an incoming pilot signal that has taken too long. The cold acquisition calculations are divided into two sub-phases where the first sub-phase searches for the code length 777415 used by

0 Fast Broadcast Channel. And in Alla get subcode phase we will find that the length of the guideline code which is 1748 7777416 within VTA Jaina phase is unknown. As for the second sub-phase, it is a search for 178 phases out of the remaining possible phases. In order to maintain synchronization with the Quick Call channel for the search phase in the second phase, it is preferable to move back and forth between following the Quick Broadcast channel and trying to acquire the guide code.

Yo The wireless carrier station short term acquisition beacons are used by the system modem of the wireless carrier station to acquire the subscriber unit's SAXPT signal. This calculation is a fast search because the short-range communication channel beacons are a sequence of short code of given (N) length; where 17 = the number of chips per symbol which ranges from £0 to 140 chips;

119 - Knowing the phase of the subscriber's unit code through several continuous codes; In the ideal embodiment associated with the invention we will find phases ranging from 7 to 7 + 7 phase to search through the impedance phase generated by the wireless carrier station. The deviation of the number of phases is due to the pilot signal of the subscriber unit synchronized with the international pilot signal of the wireless © carrier station. and after the accounts are re-acquired when the code reservation is lost; Z-search arithmetic is used to perform the operation faster, assuming that the phase of the code does not deviate too far from its previous position when the system is off. The wireless carrier station uses the maximum width of the search windows (2) associated with the maximum phase of the diffuse equation. ye The pre-follow-up phase directly follows the acquisition and re-acquisition calculations; It also precedes the follow-up calculations. The pre-follow-up phase is carried out over a second time period; The receiver data provided by the modem is not static. The pre-tracking stage allows other calculations to be made, such as those used by (YVY¢) ISWPLL, (VVYYY) AMF WEIGHT GEN, TRACKING, to be configured according to the current channel. The pre-follow stage is divided into two parts - the first part is the impedance when the code follow-up circuit pulls in; While the second part is an impedance when carrying out weight calculations (eB pally pal ad) compatible adapter by AMF WEIGHT GEN (1777), to give a constant weight coefficient. By (1774) SWPLL 0 and the numerical quantity is estimated in the quantity estimator 1777 (a). \VYYV

The follow-up process is introduced after the completion of the pre-follow-up phase. This process is repeated de times ¢ and in this phase only the receiver data emitted by the modem is considered stable. The following are the operations that are performed during this phase. - Updated compatible filter weight adapter.

In the event that the loss of the code reservation is detected; The modem receiver terminates the follow-up accounts and directly enters the re-acquisition accounts. In the subscriber unit, the loss of the code reservation causes the bus to close. At the Jalal Wireless Station, the loss of the code reservation causes the power control to shift

vo forward to impede carrier energy set at a fixed level immediately prior to loss of reservation; It also causes feed back power control data transmitted assuming Yo Vo mode) which causes off which causes the subscriber unit to hold bus power stably. This can be implemented using a signal test function that generates a reset signal to the acquisition and follow-up circuit (170).

1171 - - Two sets of quantitative statistics are prepared through the quantitative estimate device 1777 (b) and the numerical quantitative estimate device 1777 (a). Both devices are used by the modem controller (TY). The first set includes quantitative vector data; It is so named since 0 is computed from the vector of four composite values generated by the receiver of the adapter vector coupling of (071) AUX. The second group includes quantitative data on the number as it is computed from the simple composite value of the emitted AUX signal From the AUX (VY eV) collector The two datasets represent two different sets of noise statistics which are used to generate a pre-determined potential false alarm The vector quantum data is used by the 0 calculations of acquisition and reacquisition performed by the control device modem (VF) to determine how far a received signal appears in the noise, while scalar quantity Aad gy is used closed code test calculations. In both vector and scalar cases, the quantity data includes computed values for from zero to lambda"; these values are considered boundary values Used to estimate the potential distribution function of the collected 1 receiver signal and to determine if the modem is connected to a false noise code; the value of AUX- Power in the following © subprogram is the square measure of the output of the AUX signal of 5 quantitative scalar couplers directed; The total value is squared expressions to specify the directed state. In both cases, the quantities are calculated using the following subprogram 0: a

During the acquisition phase, the process of searching for the pilot signal coming with the internally generated pilot code sequences uses a series of tests to determine whether the internally generated pilot code has the correct code phase for the signal (Al J) or not. Cad calculations use a sequence probability ratio check to determine if the received and generated code sequences are 0 internally in phase first and the acquisition speed is increased by the parallelism resulting from the presence of a multi-board (finger) receiver. For example, in the embodiment shown, the sloped (WY) pilot has a total number of plates (fingers) of 11 Jad plates (become) a phase consisting of 11 slatted stages; In order to achieve the acquisition, A tests are performed to check the probability of sequencing ratio so that each process of checking the sequencing probability ratio is monitored; windows. Each window is 1 slide away from the window preceding it; In the sequential search process, the code phase is covered by four windows. And in the Alla reject A tests to check the likelihood ratio of the sequence A segments are added on the set of windows. In the event that any of the sequence probability ratio tests are accepted, the code phase of the internally generated guideline code sequence is modified in an attempt to centralize the Gall phase of the sequence probability ratio examination on it; It is done through the guideline's vector binding tool.

The plate output level values are denoted (fingers) to [e] 1 Q Finger [n] Finger 0.

The interface controller IC (1717) of the subscriber line interface (YY) +) emits a digital information signal TINF which is the input signal to the ADPCM decoder (171) if the user information signal is ADPCM encrypted as a POTS service and for data encrypted or unencrypted ADPCM user information; the (717) IC 0 data message passes the TDMESS directly to the interface (7771). The call control meter (77) is derived including the subscriber line interface (7701). All call control information is derived from the user information signal and the call control information (CCINF) is passed to the control device in the SU (1771). The (YYYY) ADPCM decoder receives the encoding signals and the Jalal modulation signals from the control device of the (777001) SU and converts an input signal of the digital information into a traffic signal of the output message TVMESS in response to the encoding signals and the modulating carrier signals The SU controller also emits (YY) the inverse control signal which includes the control information of the coding signal call and modulation signal J modem 00118. The output message signal TVMESS is applied to the data interface.) 77710) and the data interface (1"701) sends user information to the CDMA modem (0.77) as a TMESS (Yee) message signal. The CDMA modem (0.71) publishes Output signal and reverse link control channels TCTRL received from SU controller (1777); backlink CSMA signal is output and backlink CDMA signal is supplied to RF transmitter (17010) and modulated by a
