摘要: p 是奇素数,n 为一正偶数,且满足gcd(n - 1p + 1) = 1 。令d = (pn - 1 + 1)/(p + 1) ,α 是有限域Fpn 的本原元,研究了周期为pn - 1 的p 元m 序列{tr n1 (αt)} 与其采样序列{tr n1 (αdt)} 之间的互相关性,确定了相关函数Cd (τ) 的所有可能取值,并得到了|Cd (τ) + 1| £ pn/2 + 1 的概率。当n 充分大时,该概率接近1 。

Abstract:
Let p be an odd prime and n be even positive integer with gcd(n - 1p + 1) = 1 .For d = (pn - 1 + 1)/(p + 1) ,the crosscorrelation between the p -ary m -sequence {tr n1 (αt)} and its decimated sequence {tr n1 (αdt)} is investigated,where α is the primitive element of Fpn .The possible values of the crosscorrelation function Cd (τ) are determined and the probability of|Cd (τ) + 1| £ pn/2 + 1 is also determined.When n is big enough,this probability approximates to 1 .
Key words: cross-correlation function, exponential sum, p -ary m -sequences, finite fields
