METHOD AND DEVICE FOR REDUCING CHANNEL-TYPE INBAND FREQUENCY-MODULATED NOISE IN DIGITAL SOUND BROADCAST SYSTEM Russian patent published in 2004 - IPC

Abstract RU 2225070 C2

FIELD: digital sound broadcast systems. SUBSTANCE: method includes reception of composite signal incorporating sought signal and noise signal and normalization of composite signal to obtain normalized composite signal. Then composite signal is multiplied by adjoin value of normalized composite signal to obtain actual signal; the latter is filtered off and resultant filtered-off signal is multiplied by normalized composite signal to obtain output signal. EFFECT: reduced impact of noise signal upon output signal that facilitates detection of sought signal. 18 cl, 5 dwg
