A method for transmitting data via multiple antennas by modulating data to be transmitted into a plurality of modulated symbols, encoding each pair of modulated symbols from said plurality of symbols in accordance with a transmission diversity to result in N by N matrices, with each N by N matrix corresponding to each pair of modulated symbols, generating a M by M code matrix comprised of the N by N matrices, orthogonally spreading the M by M code matrix to generate an output matrix, generating a plurality of row-permuted matrices by exchanging at least one pair of rows in the output matrix, and transmitting the symbols in the plurality of row-permuted matrices via a plurality of antennas by using either a space time transmission diversity, a space frequency transmission diversity, or a combination of a space time transmission diversity and a space frequency transmission diversity.

Procédé de transmission de données via plusieurs antennes par modulation des données à transmettre en plusieurs symboles modulés, codage de chaque paire de symboles modulés dans cette pluralité de symboles selon une diversité de transmission pour donner des matrices N par N, chaque matrice correspondant à chaque paire de symboles modulés, production de matrice de code M par M constituée des matrices N par N, étalement orthogonal de la matrice de code pour donner une matrice de sortie, production de plusieurs matrices à permutation de rangée par échange d'au moins une paire de rangées dans la matrice de sortie, et transmission des symboles dans la pluralité de matrices à permutation de rangée via plusieurs antennes, soit en diversité de transmission spatio-temporelle, soit en diversité de transmission spatio-fréquencielle, soit en combinaison de ces deux modes de transmission en diversité
