Abstract

Efficient RF power amplifiers used in third generation systems ( like wide-band WCDMA systems ) require linearization in order to reduce adjacent channel inter-modulation distortion, without sacrificing efficiency. This paper presents a new adaptive digital base-band predistortion system based on look-up table (LUT) called the slope-dependent method, and compares it with the direct linear-LUT used by Cavers, by analysing their performance and convergence time when applied to a wide band signal ( like W-CDMA ) input.
