Patent ID: 7925230

Claim:
A diversity receiver, comprising: a plurality of antennas configured to receive radio frequency signals; a plurality of receiver circuits each coupled to a respective one of the plurality of antennas and configured to process the received radio frequency signals; a channel estimator coupled to at least one of the receiver circuits and configured to determine at least one channel estimation value corresponding to a transfer function of a transmission channel at a given carrier frequency for the respective received radio frequency signals; and a controller coupled to the channel estimator and to at least one of the receiver circuits, and configured to selectively activate and deactivate the at least one receiver circuit depending on the determined at least one of channel estimation value, wherein: a first plurality of the antennas and the receiver circuits coupled to the first plurality of antennas form a first group, and the channel estimator is coupled to the receiver circuits of the first group and is configured to determine channel estimation values for the radio frequency signals received by the antennas of the first group.
