摘要
首先简要介绍了通信系统中接收机灵敏度和系统电平余量的概念，然后着重分析了在不同的扩频通信系统中这两项指标的估算方法，最后总结了各种系统的特点。
In this article, we introduce the concept of receiver sensitivity and system fading margin in telecommunication systems and the method of calculating these two indicators in various spread spectrum(SS) telecommunication systems. In the end, we analyze the performance of various SS telecommunication systems.
