A Comparative Overview of Digital Predistortion Behavioral Modeling for Multi-standards Applications

This work proposes a comparative study of three Digital predistortion (DPD) models, TPM (Two Path Memory based Volterra), GMP (Generalized Memory Polynomial), DDR (Dynamic Deviation Reduction) for multi standard system operation purpose. This paper is an extension of our previous work based on simulation data sets [1]. This assessment is conducted through measurements on a Silicon Bipolar Darlington Amplifier in two parts: the DPD models identification first, then their emulation with MATLAB in a specific measurements test bench to evaluate each DPD model with the power amplifier (PA).
