Abstract:
A method and system for wireless communication is provided and may include generating a single analog quadrature signal in a chip including RF transmitters and receivers using a baseband processor, and generating output RF signals based on the quadrature signal in corresponding RF transmitters. The output RF signals may be communicated to the RF receivers via a feedback path including circuitry external to the RF receivers. The dedicated circuitry may include a transmit/receive switch and/or an on-chip or off-chip balun. The quadrature signal may include in-phase and quadrature-phase components. The output RF signal communicated via the feedback path may be down-converted utilizing mixers in the RF receivers and communicated to the baseband processor. Distortion in the quadrature signal may be estimated utilizing the communicated down-converted output RF signals and subsequently generated quadrature signals may be predistorted based on the distortion estimation.
