Distributed source coding via linear block codes: A general framework for multiple sources

Abstract

In this paper, we propose a general framework for Distributed Source Coding (DSC) of multiple sequentially correlated information sources. In particular, we modularize the joint decoding function into a conceptually simple structure by utilizing a notion of "complementarity" on the code space. Assuming a constrained Hamming-distance based correlation, our general framework of DSC achieves arbitrary non-asymmetric-rate compression of multiple sources with a same overall compression rate as asymmetric compression schemes. This DSC framework does not only have flexibility with respect to compression rates, but also accommodates the use of any linear block code and any of its corresponding compl..
