Overlapped Quasi-Arithmetic Codes for Distributed Video Coding
This paper describes Slepian-Wolf codes based on overlapped quasi-arithmetic codes, where overlapping allows lossy compression of the source below its entropy. In the context of s...

A New Achievability Scheme for the Relay Channel
In this paper, we propose a new coding scheme for the general relay channel. This coding scheme is in the form of a block Markov code. The transmitter uses a superposition Markov ...

Slepian-Wolf Coding for Nonuniform Sources Using Turbo Codes
The recently proposed turbo-binning scheme is shown to be both efficient and optimal for uniform source Slepian-Wolf coding problem [1]. This paper studies the case when sources a...

Block-Adaptive Wyner-Ziv Coding for Transform-Domain Distributed Video Coding
This paper presents a transform-domain distributed video compression (DVC) system with block-adaptive Wyner-Ziv coding. In the proposed system, the source symbols are reformatted ...
