摘要: In this paper, we look at the problem of implementing high-throughput Joint Source- Channel (JSC) coding schemes for transmission binary sources with memory over AWGN channels. The are modeled either by a Markov chain (MC) or hidden model (HMM). We propose scheme based on Burrows-Wheeler Transform (BWT) and parallel concatenation Rate-Compatible Modulation Low-Density Generator Matrix (RCM-LDGM) codes. proposed uses BWT to convert original source into set independent non-uniform Discrete Memoryless (DMS) sources, which then separately encoded, optimal rates, using RCM-LDGM
