| 摘 要： | 数字预失真(DPD)是一种能有效地补偿功率放大器(PA)非线性失真的技术.基于记忆多项式预失真的非直接学习结构(ILA),采用RPE(Recursive Predlotion Error)算法构造了非线性PA的自适应预失真模型,推导了该算法在预失真系统中的递推公式,给出了计算机仿真结果,在相同参数下,通过与RLS算法在系统中的仿真结果进行比较,证明了该算法对消除PA非线性失真的有效性.

| Abstract: | Digital Predistortion (DPD) is an effective technology to compensate nonlinear distortion of power amplifier (PA). The Recursive Prediction Error (RPE) algorithm is used to construct an adaptive predistortion model of nonlinear PA based on indirect learning architecture (ILA) of memory polynomial predistortion., the recursion formulas using this algorithm in pre-distortion system are derived, the computer simulation results are given, the effectiveness to eliminate the nonlinear distortion of PA for this al... |
