CA 2369959

Apparatuses for a transmitter and a receiver (202) which enhance the performance of a system utilizing interleaving and transmit diversity by reordering the sequence of symbols transmitted along the different transmission channels. This enhancement is accomplished by providing different shuffling functions in conjunction with the interleavers (216, 218) and deinterleavers used with different transmission channels, which decreases the probability of loss of sequential symbols when transmission channels or antennas become correlated.

L'invention concerne des appareils destinés à un émetteur et à un récepteur (202) qui améliorent les performances d'un système utilisant la diversité d'intercalage et d'émission par le réarrangement de la séquence de symboles transmis à travers différentes voies de communication. Cette amélioration est possible grâce aux différentes fonctions de reclassement en conjonction avec les intercaleurs (216, 218) et les désintercaleurs utilisés avec différentes voies d'émission, ce qui a pour effet de diminuer la probabilité de perte de symboles séquentiels lorsque les canaux ou les antennes d'émission deviennent corrélés.
