Patent ID: 8126098

Claim:
A wireless receiver comprising: M antennas configured to each receive a wireless signal; front end modules configured to each receive a respective one of the wireless signals; N rake receiver modules configured to receive the wireless signals from the M antennas, wherein the N rake receiver modules are configured to combine multipath components of the wireless signals; a summing module configured to receive outputs of the N rake receiver modules, wherein the summing module is configured to sum the outputs to generate an output signal; and a receiver select module configured to detect (i) a number of the M antennas or (ii) a number of enabled receiver paths and to generate a receiver select signal based on (i) the number of the M antennas or (ii) the number of the enabled receiver paths, wherein: M and N are integers greater than 1; each of the front end modules comprises a receiver enable module; the receiver enable modules are configured to receive the receiver select signal; and the receiver select module is configured to control the receiver enable modules to selectively disable an unnecessary receiver path based on the receiver select signal.
