摘要
n级M序列是由n级非线性回馈移位寄存器产生的周期为2n的二元序列,也称为de Bruijn序列。该文将讨论M序列的对称性变换,提出了一类新的对称性变换——"与/或"逻辑对称性变换,并研究了基于对称性变换的对称群。
The M sequences of order-n are the period 2n binary sequences produced by a n-stage nonlinear feedback shift register,also referred to as de Bruijn sequences.In this paper,we deal with the symmetry transform of M sequences,a new symmetry transform for M sequences,"and / or" logical symmetry transform,is presented.The symmetry groups based on symmetry transform are studied.
