| Abstract: | On the basis of matched filter theory,the analysis is made about anti-interference performance of any modulation systems,and specially,of the DS-SS system under white random noise with any spectrum width.Then,the formulas of SNR for the systems are derived.This work is important for the electronic coutermeasures techqique. |
