摘要

本文对比特交织编码调制(BICM)传输中BICM译码和最大似然序列检测(MLSD)两种译码方案的编码误码率性能进行了理论分析。我们特别关注码字长度对误码率的影响。仿真结果表明，这种分析结果在一般调制和位-符号映射(即灰度和非灰度映射)感兴趣的信噪比制度中是准确的。

BER analysis for BICM transmission over flat fading channels using finite length codewords

This paper presents a theoretical analysis for the coded bit error rate (BER) performance of the bit-interleaved coded modulation (BICM) transmission with two decoding schemes, i.e., BICM decoding and maximum likelihood sequence detection (MLSD). We especially focus on the influence of the codeword length on the BER. The simulation results demonstrate that such analytical results are accurate in the signal-to-noise ratio regimes of interest for general modulations and bits-tosymbol mappings (i.e., Gray and non-Gray mappings).
