Abstract

A method and homodyne receiver for receiver image calibration with noise from a power amplifier are disclosed. According to one aspect, a method in a homodyne receiver includes estimating an amplitude error based at least in part on a first function of I and Q samples and estimate a phase error based at least in part on a second function of the I and Q samples, the amplitude and phase errors arising from noise that is coupled to the first receive path when a portion of transceiver circuitry of the homodyne receiver is disabled. The method also includes correcting the I and Q samples in the first receive path when the portion of transceiver circuitry of the homodyne receiver is subsequently reenabled, corrections to the I and Q samples being based at least in part on the estimated amplitude and phase error.
