1. A method for measuring receiver mixer IQ mismatch in a transceiver, the method comprising:

  • providing a training signal for a receiver mixer, the training signal having periodic, uncorrelated I and Q signals;

    determining a phase mismatch in the receiver mixer from IQ correlation over a unit period; and

    determining a gain mismatch in the receiver mixer from a power estimate of both I and Q signals for the unit period.
