一类低相关序列

A class of sequences with low crosscorrelation

给出一类d型函数,用该函数构造出了一类低相关序列集.这类序列集的周期为2n-1,集合中序列的条数为2n,其中n=4m+2.证明了其非平凡相关值只取以下4个值{-1,±2n/2-1,2n/2+1-1}.

A class of d-form function is given. For n=4m＋2, a class of d-form sequences with low crosscorrelation, period 2^n- 1 and famlily size 2^n are constructed. Also, it is proved that the nontrival crosscorrlation are { - 1, ±2^n/2 - 1,2n/2＋1 - 1 }.
