Abstract
The impact of multiple-tone jamming on acquisition performance of DSSS receiver is studied on the basis of two-dimensional correlation acquisition principle. , which makes use of DSSS receiving system modulated by BPSK and each message code is spread by integral number periods of PN code. The ideal frequency distribution of multiple-tone jamming is presented with the mathematical analysis of power spectrum of PN sequence. The multiple-tone jamming can broaden the interference domain with better performance when the carrier frequency can't be estimated accurately, and the performance of multiple-tone jamming is worse than single-tone jamming when the carrier frequency can be estimated accurately. At last, the simulation results validate the correctness of theory.关键词
