摘要

我们分析和比较了最大似然(ML)解码器和最大后验(MAP)解码器在具有正交信道的译码转发中继网络上的编码。利用中继引入误差的特定模型，推导出一种基于超网格的最优MAP解码器，该解码器可对传输码字和中继引入的误差模式进行联合估计。此外，我们还给出了ML和MAP解码错误率的解析表达式。

Error bounds for decode-and-forward relaying

We analyze and compare the maximum-likelihood (ML) decoder and the maximum a-posteriori (MAP) decoder for coding over a decode-and-forward relay network with orthogonal channels. Using a specific model for the errors introduced by the relay, we derive an optimal MAP decoder that operates on a super-trellis and estimates jointly the transmitted codeword and the error pattern introduced by the relay. Furthermore we present analytical expressions for the error rates for both ML and MAP decoding.
