摘要

枚举编码是一种很有吸引力的算法过程，用于将长源字转换为码字，反之亦然。长码字的使用使得接近一个码率尽可能接近香农的受约束信道的无噪声容量成为可能。枚举编码容易产生大量的错误传播，因为单个比特错误可能会破坏整个解码的单词。本文评估了有限行长序列的枚举编码对错误传播的影响。

Error propagation assessment of enumerative coding schemes

Enumerative coding is an attractive algorithmic procedure for translating long source words into codewords and vice versa. The usage of long codewords makes it possible to approach a code rate which is as close as desired to Shannon's noiseless capacity of the constrained channel. Enumerative encoding is prone to massive error propagation as a single bit error could ruin entire decoded words. This article evaluates the effects of error propagation of the enumerative coding of runlength limited sequences.
