直扩系统中伪码捕获的一种方法，利用FFT实现长码的捕获，对信号样本序列进行双周期补零处理-FFT code acquisition

直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。-irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high ra

在直扩通信系统中,我们可以利用FRFT进行抗宽带干扰的目的,FRFT主要针对线形调频信号-In direct sequence spread spectrum communication system, we can use FRFT anti broadband interference purposes, mainly for linear FM signal FRFT
