An algorithm about separating overlapping signals using the cyclostationary of signals is studied. On the basis of direct sequence spread system, frequency-shift filter is added into the receiver of communication system. Although the structure of frequency-shift filter is more complicated than the time-domain filter, it uses both time correlations and frequency spectrum correlations so it can (achieve) better performances for separating the overlapping signals. From the analysis of cyclostationary and frequ...
