Abstract
- Based on the prominent characteristic that the delay-multiply signals of the direct sequence spread spectral (DSSS) signals are periodical signals, the paper proposes an efficient method for the detection of DSSS signals: the detection, symbol period and chip width estimation of DSSS signals based on delay-multiply, correlation and spectrum analysis. The computer simulations show that the method can not only fit the need of the low signal to noise ratio which is quite common in the detection of DSSS signals, but also can give the estimations of the symbol period and chip width in a simple way. Especially, the proposed method can give an exact estimation of the symbol period by increasing the processed sampling data when the sampling rate is fixed, which is very important for the detection of DSSS signals.
