Wijik Lee, Ji-Youp Kim, Jong-Seon No

摘要:

令$p$是奇素数,使得$p \equiv 3\;{\rm mod}\;4$和$n$是奇整数。本文利用两个抽取的$p$元m序列$m(2t)$和$m(dt)$构造了两个新的周期为$N = \frac{p^n-1}{2}$的$p$元序列族,其中$d = 4$和$d = (p^n + 1)/2=N+1$ .利用Weil界给出了该序列族中两个序列相关值大小的上界。它们的上界被推导为$\frac{3}{\sqrt{2}} \sqrt{N+\frac{1}{2}}+\frac{1}{2}$,族大小为4N,这是序列周期的四倍。

英文摘要:

Let $p$ be an odd prime such that $p \equiv 3\;{\rm mod}\;4$ and $n$ be an odd integer. In this paper, two new families of $p$-ary sequences of period $N = \frac{p^n-1}{2}$ are constructed by two decimated $p$-ary m-sequences $m(2t)$ and $m(dt)$, where $d = 4$ and $d = (p^n + 1)/2=N+1$. The upper bound on the magnitude of correlation values of two sequences in the family is derived using Weil bound. Their upper bound is derived as $\frac{3}{\sqrt{2}} \sqrt{N+\frac{1}{2}}+\frac{1}{2}$ and the family size is 4N, which is four times the period of the sequence.
