Abstract

La présente invention concerne un procédé et un système de pondération complexe non nulle et de codage spatio-temporel de signaux destinés à une transmission sur des antennes à usage multiple (160,162,164,166). Le procédé et le système de l'invention effectuent l'extension d'un code de bloc spatio-temporel N x N' à un code de bloc spatio-temporel M x M' (M>N) en utilisant une pondération complexe non nulle des symboles intégrés au code de bloc spatio-temporel N x N' afin d'assurer la transmission du code de bloc spatio-temporel à un nombre d'antennes à réception simultanée supérieur à N'. Un résultat de M antennes à réception simultanée peut être obtenu pour M antennes d'émission.
