| 摘 要： | 依据最佳接收和匹配滤波的基本理论 ,证明了如下的结论 :尽管直接序列扩频 ( DS-SS)体制对宽带白噪声没有抗干扰的扩频增益——处理增益 ,而在干扰功率一定的条件下 ,宽带噪声干扰并不具有比窄带噪声干扰更有效的干扰效果。从而 ,澄清了在这一问题上的种种不正确的观念

| Abstract: | On the basis of the principles of optimal detection and match filter,the conclusions as the fallows are proven in this paper.Although the DS-SS system is without the spread spectrum gain to the wide band white noise interference,the interference has not bater jam effect than the narrow-band noise so long as the jammer power is constant.Therefore,some incorrect ideas on this subject are clarified. |
