Power amplifier modeling and power amplifier predistortion in OFDM system
Abstract
This paper presents a baseband predistorter to be used in OFDM systems operating with a nonlinear high power amplifier (HPA). Key features of the predistorter reside in the use of the HPA inverse structure as nonlinear distortion compensator. The performance of the compensated system is analyzed by simulations in an AWGN environment. The receiver also needs furthermore an equalizer in order to combat the distorsion effect.
