Criticism of the prototype In the prototype device for

receiving information, only part of the energy of the emitted signal is used, which potentially reduces its noise immunity.

The purpose of creating a useful model Increased noise immunity with a fuller use of the energy of the 1 received signal. Essence The goal is achieved by the fact that

instead of a UWB-singal generator, a generator of a harmonic signal was used and additionally introduced — on the transmitting side, a paraphase signal generator with a given duration, a switch and the first broadband amplifier forming a special signal with certain stably manifest pa5) meters. A characteristic feature of such a signal is a small signal base, formed by a short one, up to a few nanoseconds, with a duration of up to five quasi-half-periods (time lobes) of the common language. The width of the spectrum of the signal is determined by the formula 1

F 4-fl)

where f is the frequency ha5) of the monical signal; N is the number of quasi-half-periods.

The sigial thus formed differs from the UWB sigal of the prototia-stable signal bandwidth and power level of the emitted signals.

This ensures the operation of the device in a given frequency band and with a given level of power of the emitted radio signal so as not to interfere with other, working on the air, transmission and reception devices and information. On the other side, the following additional ones are used: a second broadband amplifier, a bandpass filter, at least five consecutively connected thin-level signal conditioners, an envelope extraction unit and at least three intermediate-level amplifiers connected in series. The thin-level signal generator provides consistent filtering of the special signal with certain parameters and consists of a thin-level signal filter and a thin-level signal amplifier.

The thin-level signal filter consists of pz5) allelic and serial coherent capacitor and inductor circuits, while the input of the thin-level signal filter is connected through the first choke connected to the first capacitor to the output of this filter, in addition, the input of this filter is connected through the second capacitor connected in series and the second choke with the common bus of the receiving side, with each pair of choke - capacitor made in a shielded version, and the electrical connection with a common busbar. A parallel circuit has good conductivity for the special signal used in this technical solution, and high resistance for signals with a large base - traditionally used in information transmission devices.

The serial circuit from the second co-capacitor and the second inductor has good conductivity for signals with a large base and operates on a common bus. And for a special signal used in a technical solution, this serial circuit is characterized by poor conductivity and does not affect its proximity to the output of the actual filter.

selection by the power of this special CIS tank. They are designed to protect against powerful interference. Small tense does not open the bottom and completely enters the next element of the chain. A powerful obstacle of that different polarity will open one of the short-circuit diodes and go to the device without causing harm to the elements of the front side.

The envelope extraction unit generates an intermediate level signal. Which, having passed the signal amplifiers of the intermediate level, is converted into an information signal and a calculated input of the trigger. Using a trigger, the information signal is converted to the form necessary} for subsequent processing in the consumer of information.

A special signal with certain stable manifesting parameters, band-pass and consistent filtering, as well as power selection of a special signal used as a data carrier can increase the noise immunity. In this case, the entire energy of the emitted signal is used, in contrast to the prototype.

Entry into these two sides of the transmitting and receiving sides is organized by the protocol of exchanging the program level at the source and consumer of information.

The essential features listed above in the interaction, ensuring the achievement of the set goal, increase noise immunity. The presence of other features: additionally introduced elements and other connections between the entire totality of elements, as well as the achievement of enhanced properties - increasing the noise immunity of the device for transmitting and receiving information allows us to conclude that the claimed utility model meets the criteria for communication and significant differences.

(see Fig. 1), containing on the transmitting side an information source 1, differentiating 2 circuits emitting 3 x-ray) and the first power supply 4, and on the front side - the receiving 5 antennas, the second power supply 6 and trigger 7 with a counting input, 8 information connected to the consumer, containing additionally entered:

a logical 9th element And sequentially connected, a generator of 10 basic signals with a given duration, a switch 11 and a first broadband 12 amplifier, and a generator 13 ge5) of a malfunctioning signal is connected to the third input of the switch 11, in addition, the first power supply 4 is connected via the corresponding network 14 filters with all elements of the transmitting side except the radiating 3 antennas; on the receiving side, the output of the receiving 5 antenna is connected to the counting input of trigger 7 through additionally introduced in series connected second broadband 15 amplifier, bandpass 16 filter, five serially connected shapers 17 of the thin fow signal, the selection unit 18 of the receiver and three series-connected amplifiers 19 1 of the intermediate level, at this, the formers of the signal of the current level consist of sequentially connected the filter 20 of the thin level signal amplifier and the amplifier 21 of the thin level signal, while a thin level signal amplifier 21 is the output of a thin level sigal driver 17, in addition to the Tosha level signal driver 17, the output of a thin level signal amplifier 21 is connected to the screen 22 of the receiving side of the device through two parallel and counter-active diodes 23 and 24, when this all the elements of the transmitting side except these diodes and the receiving 5 antennas are connected through a corresponding network 14 filters with the second power supply 6; in addition, all elements of the device except antennas 3 and 5 are made in shielded design, and the screens 22 of the transmitting and receiving sides are common bus 25 for each of them, in addition, the thin-level signal filter 17 consists of two co-IDs 26, 27 and two chokes 28, 29, at the same time, the input of the fine-level signal filter is connected through the first 28 choke and the first 26 capacitor connected in parallel with the output of this 17 filter, in addition, the input of this 17 filter is connected through the second 27 capacitor and the second 29 dross s general schnnoy 25, wherein each pa5) and throttling capacitor

The device operates as follows. On the transmitting side of source 1, the information will generate a pulse-frequency pulse signal of end 1, see Fz. 2, which, passing through the differentiating 2 circuit, is converted to 1 ШДУ 2 and enters through the logical 9 element If on the form-wagel 10 paraphase signals. At the first and second outputs of which signals of the form 3 are generated, respectively, arriving at the first and second inputs of the switch 11. A harmonic signal from the generator 13 of the pfmonial signal is fed to the third input of this switch 11. The switch passes a part of gg5 of the monical signal of the given length. Which provides the formation of a harmonic special signal, including up to five quasi-creep-tteriodes of a harmonic signal. The width of the spectrum of the same sigial is determined by formula (1). At the output of the commutator 11, the signal takes the form 4, is amplified in the first amplifier strip 12 of the amplifier, and an emitting 3 antenna is supplied. As a result, a signal is formed with a short, up to a few iaosecond, duration and a wide, up to several hundred megahertz, frequency band. A signal with such parameters has increased passability through various obstacles. It is known that SPSh signatures are used to zoid the submitted structures and orders. Electromagnetic waves reach the receiving 5th anteii, are converted into an electric wave of type 5 and enter through a second flat-band 15 amplifier to a band-pass 16 filter. The broadband of the second 15 amplifier and the passband of this 16 filters correspond to the frequency band of the emitted signal. At the output of the band-pass 16 filter, a signal of the form 6 is extracted and a transmitter of a signal of the current level is bought up by 17. In which the matched filtering is performed in the same filter 20, the amplification in the amplifier is 21 of the same level and the diodes 23, 24 are selected with respect to the power level, the essence of the matched filtering consists in isolating a special signal used in this technical solution, which differs in short duration in absolute magnitude — up to a few nanoseconds, but also relative — up to five quasi- half-periods of high-frequency occupation, in our case, a harmonic signal, although limited for others s high-zapolieiiya not. In the matched 20 signal filter of the current level, the parallel circuit from the first 26 capacitor and the first 28 inductor has a low Q factor matched to

special cigal and passes it to the username 21 sigal of a thin level. The signals traditionally used in radio communications in this circuit are attenuated. The serial circuit from the second 27 capacitor and the second 29 throttle does not pass our special signal Ia 22, but shouches the traditional radio signals. The following combination of the above circuits: 26-28 and 27-29 provides the separation of our special signal and the attenuation of the radio signals of other radio stations. Diodes 23, 24 protect the subsequent elements of the receiving side from powerful interference, for example, from lightning discharges or radar pulses. The device uses at least three thin-level signal shaper 17 connected in series, which ensures high quality consistent filtering necessary to meet the high requirements of users of information transmission and reception devices. At the output of the shaper 17, the sigal acquires form 7, enters the envelope extraction unit 18 and takes the form of the form 8. This block 18 drains and selects our special sigal for a duration equal to the duration of the transmitted signal. In the amplifier 19 of the intermediate level, a signal is generated that controls the operation of the trigger 7 on the counted input}. At the output of the trigger 7, a signal of the form 9 is formed, which arrives at the input of the consumer 8 of the information. The sychroization of the transmission and reception of information is organized by the exchange protocol at the program level in source 1 and user 8 and format.

Effective Offered Transmission Device

and receiving information increases the noise immunity of radio communications through the use of signals previously not used in communication. Traditional radio equipment uses oscillatory circuits with high quality factor to amplify signals in a certain frequency band. At the same time, the durations of the signals used are sufficient to swing the oscillatory circuit of the receiver and includes up to several tens and even hundreds of periods of high-frequency filling. The traditional battery is protected from short impulse signals, which are an obstacle. In the claimed technical solution, traditional signals are a hindrance, and a short (special) signal is a carrier of information. CoBOK TOiocTb of such special signals organized by the exchange protocol has a high noise immunity. The difference in the time scales of the information and special signals makes it possible to organize a multilevel organization of the exchange protocol, for example, similar to the myoglio organization presented in p. 19 in the article by S. Bunnn Back to hertz, see Radio No. 7, 1990, and raise the noise immunity to the required level.
