Abstract
According to the nonlinear amplification characteristic with memory effection of power amplifier (PA) in WCDMA systems, digital predistorter model is established and an identification algorithm for Wiener PA model with memory is proposed. The method can avoid the local convergence problem of NG algorithm effectively. Moreover it has a very good suppression of signal spectral regrowth. Theoretical analysis and computer simulation verified the effectiveness and practicability of the algorithm.
