METHOD AND APPARATUS FOR THE CANCELLATION OF INTERMODULATION AND HARMONIC DISTORTION IN A BASEBAND RECEIVER

摘要

A method (600) and apparatus (200) cancel odd-order distortion signals. Desensitization can be determined (610) in a received signal caused by odd-order harmonic distortion occurring from at least one transmit signal. A baseband replica harmonic distortion signal can be generated (620) using the transmit signal. The baseband replica harmonic distortion signal can be converted (630) to a low frequency harmonic distortion signal. The low frequency harmonic distortion signal can be subtracted (640) from the received signal to cancel the odd-order distortion from the received signal to create a corrected signal.
