本文讨论了用中频积累法实现低信噪比直接序列扩频信号的解扩。分析了中频积累法的基本原理以及环路设计中的若干问题。最后
给出了通过卫星信道时的实验数据。
This paper discusses the despread of low signal to noise ratio of the direct sequence (DS)spread spectrum signals using intermediate-frequency recirculation summation loop (IFRSL).Fundamental principles of IFRSL and some problems in the loop design are described.Finally
experimental results are shown for signals through the satellite channel.
