Open the CIPO recordAbstract From the Canadian patent
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.
