Research on the Existence Detection of DSSS Signal Based on Auto-Correlation

Abstract:

In practical applications, the DSSS signal has very low power spectral density, and its application range is very wide, so in the non cooperative communication, if on the premise that the spread spectrum sequence is unaware, how to detect and estimate the existence of DSSS signal is very important, this has very strong application background. This paper introduces the time domain correlation detection method of DSSS signal, through the simulation can validate that this way can detect the existence of signal; it lays the theoretical foundation for practical application.
