Research Of Cyclic Spectrum Correlation Technology Used In DS Signal Detection And Parameters Estimation

The Spread Spectrum technology has been used widely in fields such as military and civil communications, remote sensing and orientation because of its strong anti-interference, LPI, good multi-access ability and excellent secrecy.Thus it is very difficult to detect DS/SS and estimate its parameters because of its features we mentioned above. This paper presents a method that makes use of cyclic spectrum correlation technology to detect DS/SS and estimate its parameters. Cyclic spectrum correlation technology is used to analyze the cyclostationary signal. However, DS/SS has cyclic-feature, so we can use cyclic spectrum correlation technology to detect DS/SS and estimate its parameters.This paper detailedly discussed the theory of cyclic spectrum correlation technology and simulates the theory through MATLAB. In the end, the paper gives a hardware platform based on DSP to accomplish the arithmetic. Both the simulation and the experiments proved the feasibility and superiority of cyclic spectrum correlation technology.All studies in this paper proved that cyclic spectrum correlation technology is a effective and applied method for DS/SS signal detection.
