Description

 one -

The invention relates to a radio communication technique and can be used in adaptive radio communication systems for organizing the exchange of information on channels with varying parameters.

The purpose of the invention is to increase the efficiency of establishing communication.

The drawing shows a structural electrical circuit of a radio station.

The radio station contains receiver C, decoder 2 control commands, first trigger 3, first switch 4, transmitter 5, receiver frequency synthesizer 6, optimal operating frequency selector 7, control command driver 8, transmitter synthesizer 9, memory block 19 receive frequencies, second 11 and third 12 switches, transmission frequency memory block 13, receiver frequency control block 14, transmitter frequency control block 15, second trigger 16, first element 17, third 18 and fourth 19 triggers second element 20 first 2 1 and second 22 pulse shapers, synchronizer 23, programmer 24 .. bus 25 input signal.

Device Gvo works as follows.

At the initial establishment of the communication, the operator delivers a control action through the bus 25 to the pulse shaper 21. The generated pulse transfers the trigger 16 to the logical 1 state. The logical signal 1 from the trigger 16 output goes to the inputs of the second 11 and third 12 switches and switches the controls of synthesizers 6 and 9 to blocks 14 and 15. At the same time, this signal goes to blocks 10 and 13 and permits switching of receiver 1 and transmitter 5 according to programs of changing fixed frequencies of receiver 1 and transmitter 5 formed by the programmer 24. Synchronization of the formation of switching programs is provided by the synchronizer 23 according to the signals coming from its output s on the blocks 14 and 15 and programmer 24. In this case, blocks 14 and 15 provide a construction of the frequency synthesizer 6 and 9 in the passband of the receiver 1 and the transmitter 5 with respect to the fixed nominal frequency.

The switching of the frequencies of the receiver 1 and transmitter 5 takes place at certain time intervals. dos

triggers for tuning radio devices, selecting the optimal frequency and exchanging commands about the number of the optimal frequency according to the algorithm of operation of blocks 14 and 15, at each time interval, specified by the synchronizer 23, after switching frequencies of the receiver 1 and transmitter 5 and selecting the optimum frequency from the signal synchronizer 23, a shaper 22 is started, from the output of which the generated pulse goes to triggers 18 and 19 and sets them to a state of logical O, which from the outputs of flip-flops 18 and 19 goes to element 17 An impulse through the element 20, the second input of which receives logical 1 from the second flip-flop 16, is fed to the shaper 8, block 7 to request the optimal frequency, and flip-flop 3 that switches the switch 4 to the information broadcast form from shrovetel 8 to the transmitter 5. On the front of this pulse, block 7 outputs the number of the optimal frequency to switch 11 and driver B, which, by the pulse decay, encodes the number of the optimal frequency and outputs a Vogram-cog to the input of the transmitter 5 via the com- ivr fTaTop 4 management the algorithm of the block

15 in the driver B, a signal is generated which is applied to trigger 3

and sets it to the initial state, and the trigger 19, to the logical state 1. Similar operations are performed for the second correspondent. When switching the radio correspondents to frequencies affected by interference, control commands are not accepted and the radio switches synchronously to the next fixed frequencies in the program. If the next pair of frequencies turns out to be suitable for communication, then the decoders of the two correspondents select the control commands. Received: the number of the optimal operating frequency from the output of the decoder 2 is fed to the commentator 12, and the signal indicating the number of the received working frequency from the decoder 2 is fed to the trigger 18 and switches it to the logical state 1. If the signals of the logical 1 coincide with the trigger 18 and 19 element And 17 forms a signal., which arrives at the trigger

16 and translates it into the O state. The logical O signal is output from the trigger .3

Gera 16 enters blocks 10 and 13 and fixes receiver 1 and transmitter 5 at these program frequencies. At the same time, this signal goes to switches 11 and 12, which switch the control of synthesizer 6 on receiver frequencies to block 7, and synthesizer 9 on decipher 2, after which the radio correspondents switch to optimal frequencies and exchange information from external equipment to switch four.
