The invention relates to discrete communication systems and telecontrol.

Known combined line of communication on the author. St. No. 253181g

However, the known lin of communication does not provide high throughput.

The aim of the invention is to increase the capacity of the communication line.

To do this, on the transmitting and receiving sides, AND elements are connected to the analyzer outputs, and on the transmitting side, the second input of the AND element is connected to the output of the clock generator, and the output is connected to the input of the composite signal generator, and on the receiving side, the second input of the AND element is connected to the output system, and the output is connected to the inputs of the decision block and the former composite signal.

The drawing shows a structural electrical circuit of the communication line.

On the transmitting side 1 of the combined communication showers, a 2 M-sequence generator is switched on, the input of which receives impulses from the clock pulse number generator 3. The generator 2 is connected to a two-phase modulator 4 and to the adder 5, the output signal of which is fed to the analyzer 6 information elements. It is connected to the element 7 and the message transfer synchronizer 8. The output of the element 7 is connected to the driver of the composite signal 9, the signal from which is sent to the source of messages 10. The latter is connected to the synchronizer 8, the output of which is connected to a two-phase modulator 4. The output of the latter connected to modulator 11,

On the receiving side 12 of the combined communication line, the tracking system 13 is switched on, which receives the received signal from the detector receiver 14 output. The output of the monitor system 13 is connected to the adder 15 and lerimodnik 16, to the second input of which the schm is received signal from the detector output 14. Totalizer output 15 is connected to the input of the analyzer 17. The output of the analyzer is connected to the second input of the And 18 element, the output of which is connected to the decision block 19 and the composite signal shaper 20. Output ,, & tel 2O is connected to the threshold y; /R. . 21, which is connected to the recipient of the messages 22. The combined link works in the following way. From the output of generator 2, a sequence of pulses is fed to the input of the sum-torus 5 and to a two-phase modulator 4. At the output of the adder 5, an M-sequence is formed corresponding to the structure of the error signal of the tracking system used on the receiving side. This sequence goes to the analyzer 6 information elements, which reveals in it the presence of groups containing K and more zero elements of the order (K 2). When such an rpy is created, the analyzer 6 produces a strobe pulse that permits the passage through these ator 8 character messages coming from the source 10 "Simultaneously strobe pulses from the output of the analyzer 6 provided to AND gate 7 where their separation is effected into individual pulses, the time of occurrence of which coincides with the time information items pryuhozhdeni M - sequences. While the shaper counter 9 is not filled, the same symbol is sent from the source of messages Yu to the sync controller 8 When the shaper counter is filled from its output to the message source Yu, a signal is received allowing the input of the next character of the transmitted message. Consequently, the composite signal generator counter is triggered from each information element. At the receiving side, the signal from the output of the detector 14 enters the tracking system 13, as a result of which the output M-sequences are synchronized with respect to the input signal. The signal from the output of the multiplier 16 moves to the decisive unit 19 then operates at the time of arrival of the information elements of the signal. Turn it on and off i -: - yp..j-v:.; -,;.,;. ::; .l.h.pulses, formed by "iwfc:.; rfi | fcu:, / lads-shotshot adder 15, accelerator 1.7 and the domain 18 And similar to the way the cake is made during transmission. At the same time, the strc-I1 pulses from the output of the element And 18 are fed to the input of the imaging device 20, which is displayed as a pulse counter. This counter is triggered at the same time as the information elements. As long as the counter foriro 2O is not filled, in threshold device 21, the summation of single-element elements (for example, units) occurs, the output from the output of its block 1 9, by filling in the counting threshold device 21 of the received message symbol. Tie filling the counter of the formaker 2O from eio output to the account of the cnc of threshold device 21 is sent to the UI1UyAc Resetting. Thus, on the straight side 12 of the interconnected communication line, the information elements used to transmit one character of the message are summed, and the final decision on the value of the received symbol is generated based on the application of the marginal criterion. Invention Formula Combined Line by Aut. St. No. 253181 in connection with the fact that, in order to increase the throughput, elements And are connected to the analyzer outputs on the transmitting and receiving side, and the second input of the I element is connected to the output of the clock pulse generator on the transmitting side and the output is connected to the input of the former of the composite signal, and on the receiving side the second input of the AND element is connected to the output of the tracking system, and the output is connected to the inputs of the decisive unit and the former of the composite signal.
