Patent

CA 2569641

A method and apparatus is disclosed for reducing multi-user processing at the receiver (22) in wireless communication systems. Detected codes (32) are grouped according to channel impulse response and a parent code (36) is identified for each group of detected codes. A matrix A (40) is constructed and joint detection (42) is performed using the identified parent codes. Data symbols of the detected codes are obtained from the data symbols of the identified parent codes.

La présente invention concerne un procédé et un appareil conçus pour réduire un traitement multi-utilisateur au niveau du récepteur dans des systèmes de communication sans fil. Des codes détectés sont groupés en fonction d'une réponse impulsionnelle de voie et un code parent est identifié pour chaque groupe de codes détectés. Une matrice A est établie et une détection conjointe est effectuée au moyen des codes parents identifiés. Des symboles de données des codes détectés sont obtenus à partir des symboles de données des codes parents identifiés.
