摘要:

基于Ness和Helleseth等人对二元不同周期的m序列之间的互相关函数的研究,研究了不同周期的p元m序列之间的互相关性质,给出了周期为p2m-1和pm-1的m序列之间的互相关函数所满足的方程,同时证明了当p等于3时,互相关函数至少是3个值的.

关键词: 自相关, 互相关, m序列, Kasami序列

Abstract:

Recently, Ness and Helleseth initiated studies on the cross-correlation between two binary m-sequences of different periods. Based on their results, we analyse the properties of the cross-correlation between two p-ary m-sequences of different periods, and give the equations for the cross-correlation values to be met. Finally, for p=3, it is proved that the cross-correlation values takes on at least three different values.

Key words: autocorrelation, cross-correlation, m-sequence, Kasami sequence
