Techniques for calibrating a transceiver of a communication device

A technique for calibrating a transceiver of a wireless communication device includes selectively coupling an output node of a transmitter of the transceiver to an input node of a receiver of the transceiver. A calibration signal is provided, from the output node of the transmitter, to the input nod...

description A technique for calibrating a transceiver of a wireless communication device includes selectively coupling an output node of a transmitter of the transceiver to an input node of a receiver of the transceiver. A calibration signal is provided, from the output node of the transmitter, to the input node of the receiver. The calibration signal is down-converted, with the receiver, to provide a down-converted calibration signal. A discrete Fourier transform is performed on the down-converted calibration signal. Finally, one or more correction factors are determined based on an analysis of the discrete Fourier transform of the down-converted calibration signal. At least one of the correction factors is utilized to facilitate substantial cancellation of a direct current offset associated with the transceiver.
