DIFFERENTIAL PHASE-SHIFT KEYED SIGNAL DEMODULATOR Russian patent published in 2012 - IPC H04L27/22 H03D3/02

Abstract RU 2460225 C1

FIELD: information technology.

SUBSTANCE: signal autocorrelation function is generated, integrated and compared with a threshold value, which is generated depending on presence of a demodulated logic '1' or '0' signal on the previous cycle, for which a generating unit connected to the output of a resolver is further used, said generating unit consisting of a threshold former, a switch, a threshold corrector and a constant switch.

EFFECT: high noise-immunity of demodulating differential phase-shift keyed signals.
