Abstract: A communication device including: a transmitter for providing a first radio frequency (RF) signal to a first antenna; a second antenna for receiving the first RF signal from the first antenna to produce a second RF signal; a receiver for receiving the second RF signal from the second antenna, wherein the receiver generates a feedback signal from the second RF signal; and a controller configured to control pre-distortion based on the feedback signal.
