摘要:
A method for processing signals in a receiver includes receiving a plurality of wireless signals via a plurality of M receive antennas coupled to M corresponding signal amplifiers. The method may also include measuring corresponding signal strengths of M signals generated when each of M phase-shifters is coupled to each of the M receive antennas, while one or more of the M signal amplifiers are disabled. One of the M generated signals may be selected for processing without the use of an antenna switch, where the selecting may be based on the measured signal strength. Each of the plurality of received wireless signals may be amplified prior to the measuring. One or both of an in-phase (I) component and/or a quadrature (Q) component may be generated for each of the M generated signals.
