摘要
Systems and techniques relating to IQ mismatch estimation and compensation are described. A described technique includes obtaining samples of a received signal via circuitry having an IQ mismatch; determining an estimated gain imbalance parameter for the IQ mismatch based on an in-phase average value of in-phase training samples and a quadrature average value of quadrature training samples; determining an estimated phase imbalance parameter for the IQ mismatch based on a combined average value, the estimated gain imbalance parameter, and a squared average value, the combined average value being based on a pair-wise multiplication of the in-phase training samples and the quadrature training samples, the squared average value being based on squared versions of the in-phase training samples; updating the in-phase data samples based on the estimated gain imbalance parameter to produce updated in-phase data samples; and updating the quadrature data samples by respectively adding quadrature update values thereto.
