METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNALS REPRESENTED BY SPECTRAL-MODULATION DECOMPOSITION PARAMETERS Russian patent published in 2004 - IPC

Abstract RU 2224359 C1

FIELD: radio engineering. SUBSTANCE: known method involves in addition spectral- modulation decomposition of signal, including division of each band analog signal into several high and low sidebands and extraction of Hilbert amplitude envelope and instant frequency, and then quasi-constant parameters of which part is used to divide signal into sidebands. Extracted parameters are numbered and then transferred to receiving end wherein they are used to recover analog signal. EFFECT: enhanced quality and reduced speed of information message transmission. 1 cl, 6 dwg, 2 tbl
