Abstract

In order to analyze and process PN-BPSK signal which is received by reconnaissance receiver, a method for PN code recognition and parameter estimation is presented based on synchronous demodulation. In the paper, characteristics of PN-BPSK signal are analyzed firstly. Based on the mathematical model analysis of PN-BPSK signal, the principles of synchronous demodulation for PN codes recognition is demonstrated, and the algorithm of parameter estimation is given. In the end, computer simulation under two different conditions is carried out. The results of computer simulation prove correctness and feasibility of this method.
