Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.

Selon l'invention, la diversité de réception dans un dispositif sans fil est commandée en réponse à des conditions de fonctionnement, à des exigences d'émission et à des paramètres de commande. La commande de la diversité permet de réduire la consommation d'énergie par activation de la diversité de réception dans des conditions données. Les conditions de fonctionnement, les exigences d'émission et les paramètres de commande sont utilisés séparément ou conjointement pour déterminer si les bénéfices de la diversité de réception multi-antenne, tels qu'une capacité de liaison supérieure, un débit de données supérieur, une puissance d'émission inférieure et un taux d'erreurs inférieur, compensent une augmentation du coût énergétique associé la diversité.
