二元周期序列4-错误序列的研究
On the 4-error sequence distribution of 2^n-periodic binary sequences
摘要
Abstract
By studying k-linear complexity of binary sequences with period 2^n,it is proposed tion of k-error linear complexity should be converted to finding error sequences with minimal that the computa- Hamming weight. Then the k-error sequences distribution that corresponds with the k-error linear complexity of sequence is dis- cussed. Based on Games-Chan algorithm, for k=4, the counting function on the k-error sequences of 2^n-periodic binary sequences whose linear complexity less than 2^n and the k-error linear complexity are 2^n-1-(2^n+2^i) and 2^n-1- (2^n+2^i)+x is derived. Examples are presented to illustrate the results and checked by computer.关键词
