METHOD FOR MULTICHANNEL SIGNAL SEARCH AND DEMODULATION AND TECHNIQUE TO DEMODULATE AND DETECT DBPSK FDMA ULTRA-NARROW BAND SIGNAL

摘要

Described is a method of searching of multichannel signal and technique of demodulating and detecting DBPSK frequency division multiple access (FDMA) ultra-narrow band signal. A search is based on algorithm encompassing a signal-processing signal, and technique to demodulate and detect FDMA ultra-narrow band together with a method to increase time-frequency resolution.
