RADIO COMMUNICATION SYSTEM OF HIGH SIMULATED- ECHO STABILITY Russian patent published in 2002 - IPC

FIELD: radio communications; space and ground frequency-reuse radio links. SUBSTANCE: novelty is introduction of additional low-frequency filter, threshold shaper, comparison circuit, electronic switch, and device for optimal processing of pseudonoise signal. Radio link also has basic-message signal generator, power splitter, two amplitude modulators, antipodal signal amplifier, two transmitting-antenna feeds, two receiving- antenna feeds, adder, subtracting device, synchronous detector, amplitude limiter, basic-message demodulator, second low-frequency filter, polarization-axes control unit for receiving-antenna feeds, and synchronizer. EFFECT: enhanced simulated-echo stability of system. 2 dwg
