摘要:

利用线性分组码的距离分布可以设计变长编码方案,对变长信息进行编码,并通过较大的最小汉明距离获得较低的译码错误概率。为了便于编码,本文重点研究了$\mathcal{RM}(2,m)$上循环码的循环子码链(DPC)的距离分布,其长度为$n$,使得$\mbox{gcd}(n,q) = 1$ .本文研究了删余二阶Reed-Muller码$\mathcal{RM}(2,m)^*$在增加消息长度时的最佳DPC和相应的最佳循环子码链,并根据消息长度的增长节奏研究了最佳DPC和最佳循环子码链的两种标准。

英文摘要:

The distance profiles of linear block codes can be employed to design variational coding scheme for encoding message with variational length and getting lower decoding error probability by large minimum Hamming distance. %, e.g. the design of TFCI in CDMA and the researches on the second-order Reed-Muller code $\mathcal{RM}(2,m)$, etc. Considering convenience for encoding, we focus on the distance profiles with respect to cyclic subcode chains (DPCs) of cyclic codes over $GF(q)$ with length $n$ such that $\mbox{gcd}(n,q) = 1$. In this paper the optimum DPCs and the corresponding optimum cyclic subcode chains are investigated on the punctured second-order Reed-Muller code $\mathcal{RM}(2,m)^*$ for increasing message length, where two standards on the optimums are studied according to the rhythm of increase.
