置换信道的多集码

Multiset Codes for Permutation Channels

Mladen Kovačević, Dejan Vukobratović

摘要:

本文介绍了与置换信道上可靠信息传输问题有关的多集码的概念。研究置换信道的动机来自于某些类型的分组网络中分组的乱序传递的影响。建议的代码是一个推广的所谓的子集码,最近提出的作者。建立了多集码的一些基本性质,其中包括在Manhattan度量下它们与整数码的等价性。所提出的编码理论框架密切遵循Koetter和Kschischang提出的运营商通道。这两个数学模型在许多方面是相似的,并且基本思想以允许对这些类型的信道的编码的统一观点的方式提出。

英文摘要:

This paper introduces the notion of multiset codes as relevant to the problem of reliable information transmission over permutation channels. The motivation for studying permutation channels comes from the effect of out of order delivery of packets in some types of packet networks. The proposed codes are a generalization of the so-called subset codes, recently proposed by the authors. Some of the basic properties of multiset codes are established, among which their equivalence to integer codes under the Manhattan metric. The presented coding-theoretic framework follows closely the one proposed by Koetter and Kschischang for the operator channels. The two mathematical models are similar in many respects, and the basic idea is presented in a way which admits a unified view on coding for these types of channels.
