摘要

在低中频预失真器构架的基础上，提出了一种基于坐标变换的预失真参数估计方法，从而降低了传统数字基带预失真系统的硬件成本和数值计算量。算法将传统算法中的复数乘法转换为极坐标中的幅度乘法和相位加法，使同样的计算步骤所消耗的乘法和加法次数分别降低了75%和50%。所提算法由通用的通带Volterra非线性模型进行推导得出，证明了预失真处理算法中基带信号和低中频信号的等同适用性。对实际射频功放的测试实验结果验证了其有效性。

Abstract

Based on the low-IF digital predistortion (DPD) architecture

a coordinate transformation based low-complex coefficients estimation algorithm is proposed to reduce the hardware implementation cost and numerical calculation complexity significantly.The proposed algorithm transforms the complex multiplication of the conventional DPD coefficients estimation method to amplitude multiplication and phase addition in polar coordinates.To complete the same calculation

times of multiplications and accumulations are reduced by 75% and 50%.The algorithm is derived from the general Volterra pass-band nonlinear model

and proves the equivalency of baseband predistortion and IF predistortion.The proposed low-IF architecture and the coefficients estimation algorithm are verified by the measurement results on a practical radio frequency power amplifier.
