在扩频通信系统中,利用SAWTDL作为序列匹配滤波器可快速简便地完成DS信号的中频解扩。本文设计了一种针对突发DS信号的SAWTDL与数字匹配滤波器相结合的解扩解调系统,并对其性能进行了分析。
In the spread spectrum communication system, using SAWTDL as a sequence matched filter can quickly and easily complete the DS signal IF despreading. In this paper, a despreading demodulation system combining SAWTDL and digital matched filter for burst DS signal is designed and its performance is analyzed.
