摘要 射频功率放大器的向量开关数字预失真模型存在因所在区域样本点不足而引起的不连续问题。提出一种基于向量开关模型的数字预失真改进方法,该方法通过加入区域权重的约束条件以及交叠的区域划分方法对向量开关模型进行优化,达到消除向量开关模型不连续问题,提高模型的稳定性。仿真实验中采用30MHz的LTE信号进行实验,当原方法出现不连续时新方法可消除间断点,同时在邻道泄漏比(ACLR)指标上有近6dB改善,结果表明其具有更好的鲁棒性。 The vector-switched model of digital pre-distortion(DPD) in radio frequency amplifiers has a discontinuous problem which is caused by insufficient sampling data in their regions.An improvement approach of the digital pre-distortion based on a vector-switched model is proposed,which adds weighted constraint condition in the regions and overlapped threshold in the switching boundary to remove discontinuities of the vector-switched model.The 30MHz LTE signal is employed to do simulations.Result is shown that the proposed approach can remove discontinuous points and is almost 6dB better than original one in the adjacent channel power leakage ratio(ACLR) when discontinuities appear in original one.It is validated that proposed one is more robustness than original one.
