Abstract
An apparatus and method are provided for setting a local oscillator duty ratio based on an image distortion level. A first signal is transmitted utilizing a first X-phase path of a transmitter. Further, an image distortion level is measured in connection with the first signal. Based on the measurement, a duty ratio of a local oscillator is set, for reducing a distortion in connection with a transmission of a second signal utilizing a second Y-phase path of the transmitter.
