Study on the DS/SS Signals Despreading without the PN Sequence

QIN Yi,TIAN Bin(State Key Laboratory of Integrated Service Networks,Xidian University,Xi′an,710071,China)  
This paper reviews the detection methods for direct sequence spectrum spread communications.The self-correlated detection,fourth-order cumulant detection and the method utilizing the reprocessing of power spectrum and the subspace of DS/ SS signal are mainly considered in this paper.The fourth-order cumulant detection and the method utilizing the reprocessing of power spectrum and the subspace of DS/ SS signal can work well on lower SNR input signals.This paper focuses mainly on the methods utilizing the reprocessing of power spectrum and the subspace of DS/ SS signal to realize the periodic and sequence blind estimation of Pseudo Noise(PN) sequence from the lower Signal to Noise Ratios(SNR) DS/ SS signals.
