A method is disclosed for performing dual mode image rejection calibration
in a receiver. A first image correction factor is acquired (1302) for use
in a receiver system (15) using a first known signal associated with a
first signal band during a startup mode. The first image correction
factor is adjusted incrementally (1310) during a normal operation mode. A
radio frequency (RF) signal associated with the first signal band is
received (1324) using the first image correction factor during the normal
operation mode.
