DS-SS系统中的同步算法设计
首发时间:2011-08-11
摘要:为了对抗直接扩频序列(DS-SS)系统中由于不同步造成的性能损失,本论文提出一种适用于DS-SS系统的新型同步方案。该方案利用零相关窗互补码的理想零相关特性能够通过简单地运算进行定时同步和载波同步。理论推导结果表明,该同步方案不仅同步精度高且非常简单,易于实现。

Synchronization Alogrithm Design in DS-SS System
Abstract:In order to handle with the performance loss caused by out of sync in direct sequence spread spectrum (DS-SS) system, this paper propose a new synchronization scheme applicable to DS-SS systems. With zero correlation zone complementary codes, it can accomplish timing and carrier synchronization expediently. Theoretical derivation proves that this scheme has advantages of high sync precision and operation simple, which can be easily used in practical applications.
Keywords: DS-SS zero correlation zone complementary code synchronization
