Abstract
A transceiver in a wireless device supporting carrier aggregation may include a correction module to generate a correction signal to attenuate intermodulation distortion associated with a first transmitted communication signal. In one embodiment, the correction signal may be added to the first transmitted communication signal (a victim signal) to reduce the intermodulation distortion caused by a second transmitted communication signal (an aggressor signal). The correction signal may be generated based on the aggressor signal. In another embodiment, the correction signal may equalize or pre-distort the first transmitted communication signal.
