Abstract
A calibration module includes an absolute value module that generates first and second magnitude signals based on a first signal and a second signal, respectively. A first module generates an amplitude correction signal for a quadrature-amplitude modulated (QAM) signal based on the first and second magnitude signals. A second module generates a phase correction signal for the QAM signal based on the first signal and the second signal.
