Comparison between conventional intraframe codec and Wyner Ziv Codec

In a communication network consider a collection of (correlated) source nodes that need to communicate to a common sink node, then the distributed source coding problem is one of design system (of encoders and decoder) that optimally compresses the correlated sources. The key aspect of the design is that the source nodes are not allowed to communicate with one another. The goal of the distributed source coding problem is to design a system that approaches the optimal performance that can be obtained if the source nodes could communicate with one another. In this paper conventional Intraframe codec and Wyner codec are compared. For the implementation of Wyner Ziv Codec LDPC codes are used. LDPC codes are one of the hottest topics in coding theory today. Originally invented in the early 1960's, they have experienced an amazing comeback in the last few years. Unlike many other classes of codes LDPC codes are already equipped with very fast (probabilistic) encoding and decoding algorithms.
