Method and System for Using a Multi-RF Input Receiver For Diversity Selection
First Claim
1. A method for processing signals in a receiver, the method comprising:
- receiving a plurality of wireless signals via a plurality of M receive antennas;
setting each of M phase shifters coupled to each of said M receive antennas to operate in a bypass mode or with an arbitrary phase setting;
measuring corresponding signal strengths of M signals generated when each of said M phase-shifters is coupled to each of said M receive antennas, while at least a portion of said M receive antennas are turned off; and
selecting based on said measured signal strength, one of said M generated signals for processing without the use of an antenna switch.

Abstract
Aspects of a method and system for signal processing are disclosed and may include receiving a plurality of wireless signals via a plurality of M receive antennas. Each of M phase shifters coupled to each of the M receive antennas may be set to operate in a bypass mode or with an arbitrary phase setting. Corresponding signal strengths of M signals generated when each of the M phase-shifters is coupled to each of the M receive antennas may be measured, while at least a portion of the M receive antennas are turned off. Selecting one of the M generated signals for processing without the use of an antenna switch, based on the measured signal strength. A signal strength of each of the generated M amplified signals may be measured while turning off at least one of the plurality of M receive antennas and without the use of the phase-shifters.
