Abstract

In order to linearize power amplifiers, this study introduces a novel adaptive pre-distortion technique that may be used with non-constant envelope modulations like QAM and OFDM. The polynomial system is used before distortion. The goal is to minimize the Mean Square Error between the optimally amplified signal and the baseband-equivalent of the actual amplifier's output.
