<p>A communications device (20) includes a baseband input to receive a baseband signal. A transmitter (22) is coupled to the baseband input and generates a transmit signal based upon the baseband signal, the transmit signal having an initial transmit impairment. An auxiliary receiver (62) is coupled to the transmitter and generates a receive signal having a receive impairment therein resulting from the initial transmit impairment. A controller (21) determines a power of the baseband signal by integrating a product of the receive signal and a complex conjugate of the baseband signal, and determines a power of the receive signal by integrating a product of the baseband signal and the receive signal. The controller also determines the initial transmit impairment based upon the power of the baseband signal and the receive signal, and generates a transmit impairment compensation signal based upon the initial transmit impairment.</p> |
