摘要 随着k的增大 ,序列k错误线性复杂度的值会从线性复杂度递减到 0 .对于周期为 2的方幂的二元序列 ,Kurosawa讨论了线性复杂度和k错误线性复杂度的关系 ,给出了使得序列的k错误线性复杂度严格小于序列的线性复杂度最小的k值 .本文利用多项式的权重关系给出了使得序列k错误线性复杂度再次减小的最小k值 . With the increase of k, the k-error linear complexity will decrease to 0 from the value of the linear complexity of the sequences. For the binary sequences whose period is a power of 2, a relationship between the linear complexity and k-error linear complexity is discussed by Kurosawa, which indicates the least value of the positive integer k such that the k-error linear complexity less than linear complexity. In this paper, using the Hamming weight of polynomials, the least k is given such that the k-error linear complexity decreased again.
