ADAPTIVE SATELLITE COMMUNICATION SYSTEM Russian patent published in 2006 - IPC H04B7/185 

FIELD: radio engineering; satellite communication systems.

SUBSTANCE: central station of proposed adaptive satellite communication system has series-interconnected receiving antenna, receiver, demodulator, control unit, and message source, series-interconnected modulator, transmitter, and transmitting antenna; control inputs of transmitter and modulator are connected to respective outputs of control unit; its repeater has series-interconnected receiving antenna, receiver, filter unit, mixer, and first filter, series-interconnected transmitter and transmitting antenna, as well as frequency synthesizer whose first output is connected to second input of mixer; user station has series-interconnected antenna, receiver, demodulator, and data addressee; novelty is that newly introduced in central station are switching unit and memory unit whose output is connected through switching unit input to modulator input, that respective output of control unit is connected to integrated control inputs of switching unit and memory unit, message source output is connected through second input of switching unit to memory unit input; newly introduced in repeater are demodulator, modulator, series-interconnected multiplier, second filter, and quality signal shaper, as well as pseudorandom sequence generator whose outputs are connected to reference inputs of multiplier and demodulator; outputs of both the latter are integrated and connected to first filter output; second output of frequency synthesizer , first output of quality signal shaper, and demodulator output are connected to respective inputs of modulator whose output is connected to transmitter input; second output of quality signal shaper is connected to frequency synthesizer input.

EFFECT: enhanced noise immunity.
