$0$差错控制码的有效系统删除/插入和$L_{1}$度量(扩展版)

Efficient Systematic Deletions/Insertions of $0$'s Error Control Codes and the $L_{1}$ Metric (Extended version)

Luca G. Tallini, Nawaf Alqwaifly, Bella Bose

摘要:

本文给出了能够控制符号“$0$”的删除(称为$0$ -删除)和/或符号“$0$”的插入(称为$0$ -插入)的二进制分组系统码的一些理论和有效设计。已知控制$0$ -删除和/或$0$ -插入(称为$0$ -错误)的问题等价于在自然字母表$\mathbb{N}$上有效设计$L_{1}$度量非对称错误控制码.因此,$t$ $0$ -插入校正码实际上可以校正$t$ $0$ -错误,检测$(t+1)$ $0$ -错误,并且同时检测在每个接收的字中仅$0$ -删除或仅$0$ -插入的所有出现(简要地说,它们是$t$ -对称$0$ -纠错/ $(t+1)$ -对称$0$ -检错/全单向$0$ -检错($t$ -Sy $0$ EC/ $(t+1)$ -Sy $0$ ED/AU $0$ ED)代码)。从与$L_{1}$距离的关系出发,给出了系统码的最优设计。一般来说,对于所有的$t,k\in\mathbb{N}$,给出了一种递归方法,用于随着$n\in\mathbb{N}$的增加,将$k$信息比特编码成长度为$$ n\leq k+t\log_{2}k+o(t\log n) $$的有效系统$t$ $0$ EC/ $(t+1)$ $0$ ED/AU $0$ ED码.使用扩展欧几里德算法(EEA)通过代数手段可以有效地执行解码。

英文摘要:

This paper gives some theory and efficient design of binary block systematic codes capable of controlling the deletions of the symbol ``$0$'' (referred to as $0$-deletions) and/or the insertions of the symbol ``$0$'' (referred to as $0$-insertions). The problem of controlling $0$-deletions and/or $0$-insertions (referred to as $0$-errors) is known to be equivalent to the efficient design of $L_{1}$ metric asymmetric error control codes over the natural alphabet, $\mathbb{N}$. So, $t$ $0$-insertion correcting codes can actually correct $t$ $0$-errors, detect $(t+1)$ $0$-errors and, simultaneously, detect all occurrences of only $0$-deletions or only $0$-insertions in every received word (briefly, they are $t$-Symmetric $0$-Error Correcting/$(t+1)$-Symmetric $0$-Error Detecting/All Unidirectional $0$-Error Detecting ($t$-Sy$0$EC/$(t+1)$-Sy$0$ED/AU$0$ED) codes). From the relations with the $L_{1}$ distance, optimal systematic code designs are given. In general, for all $t,k\in\mathbb{N}$, a recursive method is presented to encode $k$ information bits into efficient systematic $t$-Sy$0$EC/$(t+1)$-Sy$0$ED/AU$0$ED codes of length $$ n\leq k+t\log_{2}k+o(t\log n) $$ as $n\in\mathbb{N}$ increases. Decoding can be efficiently performed by algebraic means using the Extended Euclidean Algorithm (EEA).
