Patent ID: 8144806

Claim:
A method comprising: receiving a signal having an in-phase component and a quadrature component; analyzing a mismatch between said in-phase component and said quadrature component; re-encoding an estimated symbol of the signal to generate a re-encoded signal, said re-encoding of said estimated symbol being based on said analyzing the mismatch; and processing the re-encoded signal using a correction function, which is a function of a correction matrix Cor, to correct said mismatch between said in-phase component and said quadrature component, wherein said correction matrix Cor is given by: Cor = 1 B_est ⋆ cos ⁡ ( T_est ) ⋆ [ B_est ⋆ cos ⁡ ( T_est 2 ) - sin ⁡ ( T_est 2 ) - B_est ⋆ cos ⁡ ( T_est 2 ) cos ⁡ ( T_est 2 ) ] , where B_est is an estimation of a substantially best value gain mismatch, and T_est is an estimation of a substantially best value phase mismatch of said in-phase component and said quadrature component.
