摘要： An apparatus and method for adaptively correcting I/Q imbalance, which is used in a receiver for correcting a received I/Q imbalanced signal to thus eliminate the I/Q imbalance. First, an interference amount caused by interference from an imbalanced in-phase signal to an imbalanced quadrature-phase signal is computed and accordingly subtracted from the quadrature-phase signal, so that a corrected quadrature-phase signal without phase imbalance is obtained. Next, a power of output in-phase signal, a power of output quadrature-phase signal, and a target are compared to thus determine an in-phase scaling factor and a quadrature-phase scaling factor. Finally, the imbalanced in-phase signal is multiplied by the in-phase scaling factor to thus obtain the output in-phase signal, and the corrected quadrature-phase signal is multiplied by the quadrature-phase scaling factor to thus obtain the output quadrature-phase signal.
