Abstract

This paper focuses on successive refinement for the Wyner-Ziv problem and layered code refinement coding scheme for the Wyner-Ziv problem consists of multistage encoders and decoders where each decoder uses all the information generated from previous encoding stages and the side information, which could be different from stage to stage. On extending successive refinability from jointly Gaussian source to the more general type of sources, the difference between the source and the side information is Gaussian and independent of the side information. A layered (successive) coding scheme using nested scalar quantization and Slepian-Wolf coding of bit planes based on LDPC codes is also described.
