Abstract (en)
[origin: WO9525386A1] A method for encoding/interleaving a source sequence of data symbols to be transmitted, to give at least two packets to be transmitted consisting of said data symbols to be transmitted and redundancy symbols. The method comprises the steps of writing (3) the data symbols to be transmitted into a basic matrix; storing the basic matrix in a first quadrant of an extended transmission matrix; performing primary (5) and secondary (6) coding along the columns and rows respectively of the basic matrix, to generate first and second redundancy symbols that are stored in second and third quadrants of the extended transmission matrix and form additional rows and columns of the basic matrix; and reading (7) the extended transmission matrix row by row (or column by column), each row (or column) of the extended transmission matrix being one of the packets to be transmitted (2).
