DETECTOR OF WIDE-BAND SIGNALS IN DIVERSITY RECEPTION Russian patent published in 2001 - IPC

FIELD: radio engineering, information reception over communication channels with wide-band signals in presence of narrow-band noise. SUBSTANCE: band of frequencies of received signal is divided into n partial channels so that not more than one narrow- band noise which is compensated in specified channel gets into each of n partial channels. Given detector has two receiving antennas, circuit selecting minimum, adder, source of reference voltage, clock pulse generator and n partial channels each incorporating three phase inverters, two narrow-band filters, four keys, two detectors, unit controlling third phase inverter, comparator, unit controlling first and second phase inverters, former of rectangular pulse, counter, three adders, commutator, two subtractors, two flip-flops, controllable amplifier, comparison circuit and threshold unit. EFFECT: raised noise immunity. 3 dwg
