| 摘 要： | 该文针对功率放大器的数字预失真技术进行了深入研究。并在经典Wiener模型的基础上，提出了一种改进的基于多项式加权的数字预失真算法。这种新算法包含加权、递归最小二乘和解加权三个部分。算法性能在MATLAB仿真软件进行了性能的验证与对比。结果表明，该算法在保持与功率放大器的传统数字预失真技术性能相当的条件下，结构更为简单。

| Abstract: | In this paper,a deep research on digital predistortion technology has been done.Improvement for the weighted polynomial digital predistortion algorithm is achieved by using classical Wiener predistortion model.The new algorithm consists of weighting,recursive least square,and de-weighting.The proposed technology is realized based on MATLAB simulation software.Comparing the results with the conventional DPD and the common power series polynomial,the new weighted classical polynomial predistortion model is simpler but owns the same effect. |
