Abstract
An RF communications technique pre-distorts the signal in the baseband prior to its being applied to the RF transmitter, to avoid producing harmonics when the resultant signal is processed by the RF transmitter. Pilot tones are used to test the channels between the base station and a remote station. The technique provides an improved way to minimize the harmonic distortion imposed by RF transmitters.
