More Information
Summary:The invention relates to a method of decoding a matrix built from concatenated elementary codes with uniform interleaving having nl lines, n2 columns and nl*n2 symbols, wherein the method comprises a process of all the lines- and columns-vectors of the matrix by symbols groups, this process comprises a first decoding for simultaneously processing all the symbols of a group of symbols according to their lines and then a second decoding for simultaneously processing all the symbols of the said group of symbols according to their columns while using extrinsic information produced in the line processing step, the symbols groups being thus successively processed in lines and in columns .
