Abstract:A kind of new method which is based on the reprocessing of the power spectrum of DS/SS signals is propose. It can solve the difficult problem of periodic detection and estimation of the PC sequence in the DS/SS signals. The results of computer simulation show that this method can work well for the lower S/N ratio input signals.
Keywords:direct sequence spread spectrum (DS/SS) signal  PC sequence  power spectrum
