Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus correlates the feedback signal to a reference transmit signal to correct time misalignments between the transmit chain and the feedback loop, wherein the reference transmit signal is generated in digital domain at an input to a transmit chain and estimates a transmit signal quality value based on the correlation.

Abstract: A method and apparatus for characterized pre-distortion calibration is provided. The method begins with the selection of a number of devices to be characterized. The number of devices selected may be a subset of a larger group of devices. The selected number of devices is then characterized. The method avoids characterizing the large group of devices. The apparatus includes a processor for performing pre-distortion calibration, a processor for averaging curves for each RF gain index on each channel, and a non-volatile memory.
