Abstract
An adaptive algorithm (RLS) based on adaptive polar rational function predistortion is presented and can be applied to adaptive linear power amplifiers in mobile transmitters. From the simulation for adaptive rational function predistorter system utilizing a two-tone signal, the complexity of implementation , the performance of convergence rate and the ability of suppressing intermodulation distortion are discussed.
