Distribution of 0 and 1 in the highest level of primitivesequences over Z/(2~e) (Ⅱ)
收藏 引用
Chinese Science Bulletin 1998年 第8期43卷 633-635页
作者: qi wenfeng and zhou jinjun department of applied mathmatics, zhengzhou information engineering institute, zhengzhou 450002, china department of applied Mathmtics Zhengzhou Information Engineering Institute Zhmgzhou China
The distribution of 0 and 1 is studied in the highest level a e-1of primitive sequences over Z/(2\+e). It is proved that the proportion of 0 (or 1) in one period of a e-1is between 40% and 60% for e≥8.

AUTOCORRELATIONS OF l-SEQUENCES WITH CERTAIN SHIFTS
收藏 引用
Journal of Electronics(china) 2007年 第4期24卷 439-442页
作者: Xu Hong qi wenfeng department of applied Mathematics Zhengzhou Information Engineering University Zhengzhou 450002 China
In this paper, the autocorrelations of maximal period Feedback with Carry Shift Register sequences (l-sequences) are discussed. For an l-sequence a with connection integer q = pe (e ≥ 2)and period T = pe-1(p-1),and f... 详细信息
