Research on Detection Method of Direct Sequence Spread Spectrum Signals

摘要

Direct Sequence Spread Spectrum (DSSS) Communication has been widely applied in Personal communications network,WLAN,the third-generation mobile communications,satellite communications systems,military tactics communications and etc,thanks to the DSSS signals' strong anti-interference ability,low probability of being intercepted and outstanding multi-access communication ability.At the same time,the Problem of estimating Signals has been of great research interest with the development of wind-band weak signals processing and communication antagonism.A new effective detection method of DSSS is proposed,combined the method of wavelet transformation with cycle spectral correlation approach,from the perspective of jamming in non-cooperation condition,and a simulation result of signals--BPSK is given.
