直接扩频序列信号伪码周期的估计

A new spectral method of periodic detection of PC sequence in lower SNR DS/SS signals

针对伪码周期截获的难题,提出了一种基于低信噪比直扩信号功率谱二次处理的新方法,理论分析和计算机仿真表明了此算法的有效性。

A kind of method which is based on the reprocessing of the power spectrum of DS/SS signals is propose. It can solve the difficult problem of periodic detection and estimation of the PC sequence in the DS/SS signals.Both theoretic and computer simulation show the effectiveness of this algorithm.
