Abstract
Digital predistortion (DPD) is an efficient technique for linearizing a power amplifier (PA) based on the identification of its inverse characteristic. In this paper, several DPD models are studied and evaluated according to different criteria which characterize accuracy performance and emphasize numerical properties for hardware implementation. The different models are evaluated using a 500-W peak Three-way Doherty power amplifier and compared according to different figures of merit.
