A new post distorter of WLAN amplifiers using Hammerstein filter

Abstract

In this paper we present an adaptive post-distortion algorithm for linearization of power amplifiers (PAs). This algorithm uses a Hammerstein filter in order to compensate the nonlinear distortions of PA, deriving the PAs inverse function. We have simulated our proposed system using advanced design system (ADS) software on an OFDM system. Simulation results… (More)
