FIELD: electrical engineering; radio communications; data transfer using noise-like signals.
SUBSTANCE: newly introduced in proposed system are shift register, switches, and counter; shift register input is connected to forward-channel transmitter phasing device and its output is connected directly and through counter to respective inputs of return-channel phasing device; switch is connected to return-channel transmitter output between antenna and controllable transmitting filter; synchronizing device of forward-channel receiver is connected to switch and to return-channel transmitter phasing device.
EFFECT: enhanced noise immunity.
