| Abstract: | This paper introduces the basic principle of DS/BPSK spread spectrum system,analyses performance of singletone jamming,provides perfect location of frequency of interfering DS/BPSK spread spectrum system,and creates a model of simulation of DS/BPSK spread spectrum system under the condition of single - tone jamming. It also provides PSD of every stages and BER under different SNR. The result demonstrates that interfering central frequency of DS/BPSK spread spectrum signal has great effect. |
