Patent ID: 7330501

Claim:
A radio frequency integrated circuit (RFIC) comprises: transmitter section operably coupled to convert outbound baseband signals into outbound radio frequency (RF) signals; receiver section operably coupled to convert inbound RF signals into inbound baseband signals, wherein the receiver section includes: a low noise amplifier operably coupled to amplify the inbound RF signals to produce amplified inbound RF signals; down-conversion module operably coupled to convert the amplified inbound RF signals into baseband in-phase components and quadrature components; orthogonal-normalizing module operably coupled to: obtain a first coefficient that is based on at least one of power of the baseband in-phase components, power of the baseband quadrature components, and cross-correlation between the baseband in-phase components and the baseband quadrature components; obtain a second coefficient that is based on at least one of the power of the baseband in-phase components, the power of the baseband quadrature components, and the cross-correlation between the baseband in-phase components and the baseband quadrature components; normalize an orthogonal relationship between the baseband in-phase components and the baseband quadrature components based on the first coefficient and the second coefficient to produce normalized in-phase components and normalized quadrature components; and baseband processor operably coupled to recapture data from the normalized in-phase and quadrature components.
