Preserved Fulltext
The problem of designing simple and energy-efficient nonlinear distributed source-channel codes is considered. By demonstrating similarities between this problem and the problem of bandwidth expansion, a structure for source-channel codes is presented and analyzed. Based on this analysis an understanding about desirable properties for such a system is gained and used to produce an explicit sourcechannel code which is then analyzed and simulated. It is shown that the code has a substantial gain compared to a linear source-channel code.
