摘要: 在n为奇数的情形下,研究了(GMW)序列和Hyperoval序列及其某一采样序列间的互相关函数。研究表明:GMW序列和Hyperoval序列及其某一采样序列间的互相关函数都可转化为m-序列与其采样序列间的互相关函数。

Abstract: For odd n,the cross-correlation functions between Gordon-Mills-Welch(GMW) sequences and Hyperoval sequences(decimated Hyperoval sequences with one particular exponent) are investigated.In this correspondence,it shows that the calculation of the cross-correlation functions between GMW sequences and Hyperoval sequences(decimated Hyperoval sequences with one particular exponent) is related to the calculation of the cross-correlation between m-sequences and their decimations.
