Abstract
A method is described for implementing a multidimensional linear block code on a frame of information symbols to be transmitted through a transmission system, the information symbols being organized in a frame with a number of columns and a number of rows. The method includes the steps of adding to the frame of information symbols a number of columns of redundancy symbols of a length equal to the number of rows of the frame of symbols to be transmitted; and of identifying the horizontal sequences, or rows, of information symbols and redundancy symbols as first code words. The redundancy symbols are constructed in such a way that, by interleaving the frame of information symbols and redundancy symbols, using a permutation of the elements within the columns, the rows of information symbols and redundancy symbols produced from the permuted columns form second code words. Conveniently, such operation may be repeated to obtain multidimensional codes.
