摘要
针对高均峰比的宽带输入信号,结合最小均方算法和Wiener模型的优点,该文提出了一种基于Wiener模型的数字预失真算法。通过计算机仿真,验证这种算法的有效性,补偿了功率放大器的非线性失真,提高了功放效率,对发射机功放线性化技术有一定的实用价值。
Based on the wide band input signal with high peak-to-average power ratios（PAPR）,the paper proposes an effective algorithm based on Wiener DPD model,which combines the advantages of LMS method and Wiener model.In the end,simulation result demonstrates that the proposed pre-distortion method is effective,and compensates HPA＇s nonlinear distortion and enhances HPA＇s efficiency.It will be helpful to the utility development of transmitter＇s amplifier linearization.
