摘要

对于奇数n

研究了Gordon-Mills-Welch(GMW)序列与Welch-Gong(WG)序列(及其某一采样序列)间的互相关函数以及WG序列间的互相关函数。研究表明:GMW序列与WG序列(及其某一采样序列)间的互相关函数以及WG序列间的互相关函数最终均与m-序列与其采样序列间的互相关函数相关;并且在一定条件下

WG序列间的互相关函数可为3-值或5-值的。另外

给出了GMW序列与WG序列间互相关函数的最大峰值。

Abstract

For odd n

the cross-correlations between Gordon-Mills-Welch（GMW） sequences and Welch-Gong（WG） sequences（decimated WG sequences with one particular exponent） and that of WG sequences were investigated.It shows that the calculations of the cross-correlation between GMW sequences and WG sequences（decimated WG sequences with one particular exponent） and that of WG sequences were all related to the cross-correlation of m-sequences and their decimations.Moreover

the cross-correlation of WG sequences can be 3-valued or 5-valued under a certain condition.Furthermore

the maximum magnitude of the cross-correlation between GMW sequences and WG sequences were given.
