RADIO LINK Russian patent published in 2001 - IPC

FIELD: radio communications; space and ground passive sonars; frequency-reuse radio communication systems. SUBSTANCE: proposed link has on sending end main-message signal generator, power splitter, first and second amplitude modulators, paraphase amplifier, and transmitting system; on receiving end it has receiving antenna, adder, subtractor, synchronous detector, amplitude limiter, demodulator, narrow- band low-frequency filter, and polarization changer. Newly introduced on sending end are frequency synthesizer, decoder, standard generator, pseudo- random sequence generator, synchronizer, and adder; introduced on receiving end are standard generator, clock generator, frequency synthesizer, divider, shift register, code converter, synchronizer, n switches, n band filters, adder, frequency mixer for first and second band filters, processing unit, and low- frequency filter. EFFECT: increased amount of data transmitted, reduced time taken for transmitted data retrieval, improved immunity to lumped and impulse noise. 4 dwg
