DEVICE FOR SUMMING SPACED SIGNALS Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: device for weight summing of spaced signals has reception channels 1.1,...1.N each including reception unit 14, delay element 15, controlled attenuator 16, detector 17, unit 18 measuring information parameter of signal, storage 19 and multiplier 20, unit 2 of coherent summing, demodulator 3, commutator 4, units, 5.1,...5.N of functional converters, averager 6, unit 7 of selection of maximum weight coefficient, memory registers 8.1,...8.N, storage 9 of corrections and control and synchronization unit 10 including pulse generator 11, pickup 12 and delay unit 13. Since with change of communication conditions maximum weight coefficients are calculated by different units 5.1,...5.N and corrections are different than ratio of legitimate signals power to noise power increases. EFFECT: improved capability for reception and processing of spaced signals. 2 dwg
