Communication signal decoding with iterative cooperation between turbo and reed-solomon decoding

Abstract: Received communication signals may be decoded according to a combined turbo-RS (Reed-Solomon) decoding technique. The turbo decoding is based on information produced by the RS decoding. (end of abstract)
