Abstract
The transmitted bits are coded according to the product of at least two systematic block codes. An iterative decoding is applied in order to determine, at each code word search step, a data matrix and a decision matrix which are used for the following step. The new decision matrix is determined at each step by decoding the rows or the columns of the input matrix, and the new data matrix is determined by taking account of correction terms which increase the reliability of the decoding at each iteration. The method is especially suited for use with high-efficiency block codes.
