Maxwell构造:迭代与最大后验译码之间的隐形桥梁

Maxwell Construction: The Hidden Bridge between Iterative and Maximum a Posteriori Decoding

Cyril Measson, Andrea Montanari, Ruediger Urbanke

摘要:

置信传播和最大后验译码之间存在着一种基本的联系。解码算法,我们称之为麦克斯韦解码器,介绍,并提供了一个建设性的描述这种关系。无论是算法本身还是对新解码器的分析,都让人想起热力学中的麦克斯韦构造。本文详细研究的情况下,传输的二进制擦除通道,而扩展到一般的二进制无记忆通道中讨论的配套文件。

英文摘要:

There is a fundamental relationship between belief propagation and maximum a posteriori decoding. A decoding algorithm, which we call the Maxwell decoder, is introduced and provides a constructive description of this relationship. Both, the algorithm itself and the analysis of the new decoder are reminiscent of the Maxwell construction in thermodynamics. This paper investigates in detail the case of transmission over the binary erasure channel, while the extension to general binary memoryless channels is discussed in a companion paper.
