主 题：cyclostationary frequency shift filter overlap signal spectral correlation
摘 要：This paper studies an algorithm about separating spectrally overlapping signals using the cyclostationary properties of *** the basis of direct sequence spread system(DSSS),frequency shift filter is added into the re-ceiver of the communication *** the structure of frequency shift filter is more complicated than the time-domain filter,it uses both time correlations and fre-quency spectrum correlations so it can achieve better per-formances on separating the overlapping *** the analysis of cyclostationary characteristic and frequency spec-trum correlation,the structure of the frequency shift filter can be ***,a self-adaptive algorithm is utilized for the purpose of achieving optimum multidimensional tap weights of frequency shift *** simulation results indi-cate that this method can efficiently separate overlapping signals,and its error rate is lower than the time-domain filter or DSSS system by two orders of magnitude on the condition that high-power interference is added into the system.
