Abstract

Practical decoders that take advantage of the source redundancy without requiring prior knowledge of the source statistics are designed. Discrete universal denoiser (DUDE)-enhanced decoders including, hard-denoising and decoding, soft-denoising and decoding, and iterative denoising and decoding, are considered. The results indicate that these decoders can provide substantial reductions in bit-error rates over conventional decoders that ignore redundancy in the source. The results involving Markov sources and repeat accumulate (RA) codes show that the proposed DUDE-enhanced belief propagation (BP) decoders closely track the performance of various source distribution dependent BP decoder structures.
