METHOD FOR RECEIVING WIDEBAND SIGNAL AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1998 - IPC

FIELD: communication. SUBSTANCE: method involves generation of space-separated channels, in each of which M adjacent frequency channels are generated, addition of signals of same-type frequency channels in all spaced receiving channels in order to achieve joined signals of frequency channels, which are added with preliminary alternation of amplitude of joined signals of frequency channels so that maximal signal-to-noise ratio is reached. Goal of invention is achieved by addition of same-type signals of frequency channels of all spaced receiving channels with some phase shift. Then method involves addition of signals of frequency channels with preliminary alternation of phase of added signals of frequency channels in order to reach maximal signal-to-noise ratio. Then signal is demodulated and maximal signal-to-noise ratio is achieved after demodulation. Corresponding device has L spaced receiving channels which outputs are connected to corresponding filtration unit, each of which has M narrow-band filters, M frequency channels, two adders, two demodulators and unit for assessing reception quality. Another claim of invention describes different design of frequency channels. EFFECT: increased stability to noise. 3 cl, 9 dwg
