The 0 ,1 - Distribution of the First CoordinateSequences Derived from ML- Sequences over Z/(2~e)

The 0,1 distribution of the first coordinate sequences derived from the maximal lenght sequences (ML sequences) over Z/(2~e) is exactly given.

New families of p-ary sequences with low correlation and large linear span

This article presents a new family of p-ary sequences. The proposed sequences are proved to have not only low correlation property, but also large linear span and large family size. Furthermore, it shows that the new family of sequences contains Tang＇s construction as a subset if m-sequences are excluded from both constructions.

GF(p~α)上钟控序列

本文利用有限域GF(p^a)(p>2为素数,a≥1为正整数)上二次特征η建立了GF(p^a)上一类互钟控序列,即LSR_g[d_0,d_1,d_2]-互钟控序列。讨论了当用作移位时钟控制的前馈函数g(x_1,x_2,……x_n)为二次型时,LSR_(?)[d_0,d_1,d_2]-互钟控序列的周期和线性复杂度的特点。
