摘要： Aspects of a method and system for compensating for estimated distortion in a transmitter by utilizing a digital predistortion scheme with a quadrature feedback mixer configuration are presented. Aspects of the system may include an RF transmitter that enables generation of an RF output signal in response to one or more generated input signals. One or more feedback signals may be generated by performing frequency downconversion on the RF output signal within a corresponding one or more feedback mixer circuits. The generated one or more feedback signals may be inserted at a corresponding one or more insertion points in an RF receiver. Each insertion point may be between a receiver mixer circuit and corresponding circuits that generate a baseband signal based on the corresponding one of the feedback signals.

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.

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.
