On the basis of the study on the Digital Predistortion(DPD) algorithm
this paper presents a DPD algorithm that accomplishes the linearization of WCDMA RF power amplifiers in 3G radio communications by using QR decomposition.It can adaptively alter the filter coefficient to compensate the nonlinearity of the power amplifiers.Simulation results indicate that this algorithm is effective and useful.
