The last chapter is the main part of this paper, and we put forward some results on the binary image of K-cyclic code, cyclic code and quasi-cyclic code over Z_4. 第3章为本文的主体部分,给出了关于环Z4上的K-循环码,循环码和准循环码的二进制像的性质的一些结果。
The characteristics of binary code disc and cyclic code disc are analyzed, and a new design of absolute code disc based on three regional models is then presented. 分析二进制码盘、循环码盘的特点,提出一种新型的具有三种区域模式的绝对式码盘设计方案。
Research on Multi-probe K-partitioning Encoding Structure and an Encoder of Binary Cyclic Code 多探头K分割编码结构及循环码编码器研究
Any column of the matrix can be permuted randomly, and the permutation between columns should satisfy the form which is the automorphism group of the binary cyclic Turbo code generated by the feedback polynomial. 该矩阵的任意一列可采用随机交织方式,而列间交织方式必须是按由反馈多项式生成的循环码字集的自同构群构成。
