【摘要】 从Gold序列、M序列这两种扩频序列的生成方式出发,对这两种序列的性能进行了分析和比较,基于Matlab平台,在传统Gold序列的基础上,以M序列为原型设计出一种改进的非线性平衡正交Gold序列,并筛选出其中的平衡序列,对其性能进行了分析。经过分析和仿真验证,这种序列是一种非线性序列,而且地址数相当多,同时有着良好的自相关和互相关性能。性能分析结果表明,这种序列适合应用于对扩频序列的性能要求苛刻的各种扩频通信系统中。更多还原

【Abstract】 On the basis of analyzing the generating ways and the correlation performances of M sequences and Gold sequences,an improved method of generating orthogonal balance Gold sequences was presented and the analysis of correlation performances was provided. By simulating the process of generating Gold sequence and analyzing its character of the auto correlation and cross correlation,the number of these sequences is large and the performances of correlation function are very nice. The results prove that the performances of the orthogonal balance Gold sequences are eligible in the spread spectrum communications.更多还原
