摘要
本文提供了计算任意［ｎ，ｋ］线性码的周期分布｛｜Ｐ＿ｉ｜：１≤ｉ≤ｎ｝与广义周期分｛｜Ｐ＿ｉ｜：１≤ｉ≤ｎ｝的方法，对任意线性码中以ｒ为周期的码字个数｜Ｄ＿ｒ｜和以ｒ为广义周期的码字个数｜Ｄ＿ｒ｜给出了一个普遍适用的上界和下界。
In this paper,a method is given to compute the period distribution(PD) and general period distribution(GPD)for all [n,k] linear codes.If|Dr| and|Dr|denote the numbers of codewords which have r(1≤r≤n) as its PD and GPD respeitively in a[n,k] linear codes,then the general lower bound and upper bound have been given to|Dr| and|Dr|.
