Abstract

An adaptive digital predistorter based on the PSO (particle swarm optimization) algorithm is developed and applied in LTE communication system. It can provide estimation and update adaptive digital pre-distortion filter coefficients. The performance of this method has been verified by means of simulation in MATLAB software. Significant reduction in distortion has been achieved. Simulation results show that wideband power amplifier have better performance based on proposed adaptive digital predistortion method.
