Title: Digital Predistortion of Power Amplifiers using Look-Up Table Method with Memory Effects
Authors: Sanjay Sharma and Amandeep Singh Sappal and Majit Singh Pattarh
Abstract: Digital pre-distortion techniques are widely used in linearization of RF power amplifiers. In this paper Look Up Table (LUT) type Adaptive Digital pre-Distortion (ADPD) is presented. In this algorithm, an output signal of the Power Amplifier (PA) is used as reference signal. This reference signal is used to update the coefficients of the LUT, so that characteristics of the PA, such as temperature dependence, do not have influence on the convergence performances. Simulation results have been presented.
Keywords: Digital pre-distortion (DPD), Error Vector Magnitude (EVM), Look Up Table (LUT), Power Amplifier (PA).
