Abstract
This paper presents two novel adaptive algorithms for a Feed-Forward Power Amplifier (FFPA) linearizer, one is based on the minimized power concept, while the other is the correlation between the input and output signal. Simulation shows that both of them could suppress the undesired signal for more than 20 dB.
