| Abstract: | According to the nonlinearity of power amplifier in WCDMA system,a digital baseband predistortion(DPD)algorithm with memory is proposed,which is based on the Volterra series.The algorithm can adaptively improve the nonlinearity of power amplifier.The results of theoretic analysis and computer simulation both verify the validity and practicability of this algorithm. |
