SATELLITE COMMUNICATION SYSTEM Russian patent published in 1998 - IPC

FIELD: wideband communication networks. SUBSTANCE: device has ground-based station of sender, ground-based station of recipient and equipment of space-borne transponder. Ground-based station of sender has serial circuit of antenna 1, synchronization signal receiver 2, demodulator 3, control signal detector 21, control unit 4, random sequence generator 22, phase modulator 23, transmitter 7, antenna 8, message source 5 and modulator 6, as well as random sequence generator 18. Ground-based station of recipient has serial circuit of antenna 9, information signal receiver 10, demodulator 11, information receiver 12, synchronization signal receiver 17, which output is connected through random sequence generator 38 to second inputs of receivers 10 and 17. Equipment of space-borne transponder has serial circuit of antenna 13, receiver 14, noise compensation unit 16, three identical serial circuits which have phase modulator 25, filtration unit 15, amplifier 27, amplitude detectors 28, adder 29, accumulation unit 24, threshold comparison gate 31, control signal generator 32, transmitter 33, adder 36, antenna 20, oscillator 35, delay unit 34, comparison unit 30, control signal generator 32. EFFECT: increased functional capabilities. 6 dwg
