Research on Detection Algorithm of DSSS Signals Under Alpha Stable Distribution Noise

The detection algorithm of direct sequence spread spectrum (DSSS) signals based on power spectrum reprocessing will significantly degrade in Alpha stable distribution noise environment, in order to solve this problem, the concept of generalized power spectrum reprocessing was proposed. On the basis of studying the generalized power spectrum reprocessing feature of the DSSS signals, the pulse spectrum was extracted as the detection feature to achieve effective detection. Simulation results show that the performance of this method have good performance both in the Alpha stable distribution noise.
