ISI信道上删余卷积编码传输的匹配译码

Matched Decoding for Punctured Convolutional Encoded Transmission Over ISI-Channels

Fabian Schuh, Andreas Schenk, Johannes B. Huber

摘要:

匹配解码是一种能够对ISI信道上的卷积编码PAM传输进行有效的最大似然序列估计的技术。最近,我们已经表明,编码器和信道的超网格可以用显着更少的状态描述,而不会损失欧几里德距离,通过引入非线性表示的网格。本文将匹配译码的概念推广到删余卷积码,并引入了一种时变的非线性网格描述。

英文摘要:

Matched decoding is a technique that enables the efficient maximum-likelihood sequence estimation of convolutionally encoded PAM-transmission over ISI-channels. Recently, we have shown that the super-trellis of encoder and channel can be described with significantly fewer states without loss in Euclidean distance, by introducing a non-linear representation of the trellis. This paper extends the matched decoding concept to punctured convolutional codes and introduces a time-variant, non-linear trellis description.
