METHOD FOR DEMODULATING DIGITAL SIGNALS Russian patent published in 2004 - IPC

Abstract RU 2236762 C1

FIELD: radio communications.

SUBSTANCE: proposed method includes measurement of communication channel pulse response during each clock interval, generation of combinations of expected signal pulses, generation of predistortion signals, calculation of difference signal by subtracting predistortion signal from signal being demodulated, calculation of estimate of transferred digital sequence characters, generation of estimate of additive interfering process, determination of clear input signal, comparison of clear signal with pulse combinations of expected signal during each clock interval, and discrimination of pulse combination of expected signal coinciding with clear input signal whose first pulse polarity is recorded.

EFFECT: enhance noise immunity in reception of digital signals.
