摘要:
分析并仿真了传统的非相干同步系统的相关性能.针对剩余码相位偏移效应对捕获性能造成的不良影响,证明了在1/△为整数的前提下,利用前后两个码位相关值相加可以克服该效应.基于该想法并在传统设计的基础上提出了非相干同步扩频捕获新算法.通过对新算法进行的仿真和分析,发现新算法的捕获性能确实比传统的捕获算法更好.
Abstract:
This paper firstly analyzes and simulates the relational performance of the conventional noncoherentsynchronization system. According to the bad impact on acquisition performance by the effect of residual codephase offset,it proves that the sum of the two successive matched filter outputs can conquer the effect if 1/ isintegral. Based on the scheme and conventional design,it puts forward a new algorithm of noncoherent syn-chronization spread spectrum acquisition. Many results and simulations are also given to show that the pro-posed algorithm has better performance than the conventional design.
