Abstract

FIELD: communication. SUBSTANCE: in agreement with proposed method of provision of duplex communication between two relay stations each relay station emits in direction of adjacent relay station and receives from it SHF signal-information carrier on one and same carrier frequency with separation of emission and reception in time given relay station with time-division multiplex of channels. In this case first relay station ensures time shift of start of discritization period of received signal relative to start of discritization period of emitted signal. Device for implementation of method presents system of duplex radio communication of two relay stations. Each relay station includes multiplexing equipment, AND gate, transmitter of channel separation-band-pass filter, change-over switch "reception-transmission", transmitter protection unit and aerial connected in series. Second separation-band-pass filter and transmitter connected in series are placed between aerial output and input of unit of synchronization of multiplexing equipment. Former of modulation pulses which second input is coupled to output of unit of synchronization of multiplexing equipment and inverter which input is tied up with second input of AND gate connected in series are placed between output of synchronization pulse generator of multiplexing equipment and controlling input of change-over switch "reception-transmission" with transmitter protection unit. Apart from mentioned selector of synchronization pulses, device of delay measurement which second input is integrated with input of former of modulation pulses and device controlling discritization period connected in series are placed between output of receiver and second input of unit of synchronization of multiplexing equipment at first relay station. Second output of device of delay measurement is connected to second input of former of modulation pulses. EFFECT: enhanced provision for duplex communication between adjacent relay stations.
