Abstract(in English) | We consider recursive decoding for binary linear block codes. We review the characteristics of recursive maximum likelihood decoding(RMLD)in[2]briefly. Then a theoretical framework is presented in term of coset operations for"lazy evaluation"where necessary operations are made only when they are required. This approach provides reduction of memory requirement as well as computational complexity. In the original RMLD algorithm, the computation is performed in a bottom-up way, in the sense that most likely vectors are computed for all cosets which are obtained by dividing the code. In the"lazy"version, the computation is performed in a top-down way, that is, locally most likely vectors are computed when it is required first time. The decoding complexity of the lazy version is much less than that of the original RMLD. |
