14-5 Non-Binary LDPC Coded Rate-Compatible Slepian-Wolf Video Coding

Abstract

Rate-compatible asymmetric Slepian-Wolf coding with non-binary low-density parity-check (LDPC) codes of moderate code length is presented. The proposed encoder and decoder are rate-compatible with only a single mother LDPC code. With the proposed scheme, better compressed rate and lower error rate than those of conventional scheme with optimized binary LDPC codes are achieved with even smaller source length.
