A system and method of pilot tone reuse. The present invention therefore provides a feedforward amplifier, comprising: an input that accepts a radio frequency signal having multiple carriers; a first control loop including a main amplifier block and a detector, wherein the first control loop generates a first carrier cancelled signal; a second control loop including a pilot generator, I/Q demodulator, vector modulator and first error amplifier block, wherein the pilot generator, I/Q demodulator and first error amplifier block amplify the first carrier cancelled signal and generates a pilot signal; a third control loop comprising a vector modulator and a second carrier cancellation detector; and a fourth control loop comprising of vector modulator, a second error amplifier block, and a pilot signal receiver for receiving the pilot signal generated by the pilot generator in the second error amplifier block such that the pilot signal is reused by the fourth control loop to thereby further cancel intermodulation distortion in the output of the main amplifier block.
