The Volterra series and polynomial based indirect learning digital predistortion methods suffer from the noise at the power amplifiers output. We propose an improvement using two robust non-polynomial functions to substitute the higher items, and utilizing the robust maximum correntropy criterion to replace the minima square error criterion. The convergence of the method is proved and simulations show its robust performance for noisy signals.
