The Detection And Parameters Estimation Of DS Signal Based On Cyclic Spectrum Correlation Technology

The Spread Spectrum technology has got wide usage upon communications, telemetry, and orientation because of its strong anti-interference ability, low probability of being intercepted and captured, strong discrimination ability, outstanding multi-access communication ability, and excellent secrecy.It is much difficult to detect DS signal because of the features above.This paper presents a method which makes use of cyclic spectrum correlation technology to detect DS signal. Cyclic spectrum correlation technology is used to analyze the cyclostational signal,on the other hand,DS signal has cyclostation. So we can make use of cyclic spectrum correlation technology to detect DS signal and estimate the parameters of DS signal. The detection and parameter estimation of DS signal are studied in this paper. Cyclic period chart spectrum estimation is used on parameter estimation. The paper gives the simulation ways of MATLAB on the method mentioned above.The study of this paper effectively improves the performance of the cyclic spectrum correlation technology and puts forward a novel method detecting DS signal.
