Embodiments described herein provide a method and apparatus for monitoring and correcting a transmit signal. A first sample is taken before the signal is input to a digital to analog converter (DAC) in a transmit chain. A second sample is taken of the transmit signal after the signal has passed through the power amplifier (PA). The first and second transmit samples are then compared and an equalizer interpolation value is determined. This equalizer interpolation value is applied to the transmit signal before transmission to provide a transmit signal with improved quality. The apparatus includes a feedback receive correction unit; a time domain processor in communication with the feedback receive correction unit; a frequency domain processing equalizer in communication with the time domain processor; an equalizer interpolation unit; an absolute value squaring unit in communication with the equalizer interpolation unit; and a processor for computation of a transmit quality parameter.
