A Feature Extraction Technique for DS Signals
Niu Jing-chang · Radio Engineering · 2010
The basic principles of DS system were introduced.In-depth analysis and research results were given on time domain correlation detection method,cyclic spectral detection method,cepstrum detection method and high-order cumulant,so as to reflect the direct sequence spread spectrum (DSSS) for the signal wave and frequency domain feature.The digital signal processing techniques were used on the DSSS signal simulation and verification feature extraction.And the performance of each detection and advantages and disadvantages were given.
