再论分组码的周期分布

More on The Period Distribution of Block Codes

本文对分组码的周期分布问题进行了更进一步的研究，得到了一批新结果。比如，揭示了周期分布与某些特殊矩阵秩之间的关系；解决了几类特殊码的周期分布问题。最后还提出了几个未解决的公开问题。

A few more new results about the period distribution of block codes are proved.For example the relationship between period distributions and ranks of some special matrices are discovered;the exact values of period distributions for a few block codes are calculated.At the end of this paper some open problems are proposed.
