Filed: 2017-12-20
Abstract: 一种数字预失真处理方法和装置，采集功率放大器的输入信号和功率放大器的输出信号（S201）。在确定采集的输入信号满足设定阈值时，根据采集的输入信号和采集的输出信号更新预失真系数（S202）。然后根据更新后的预失真系数、采集的输入信号和采集的输出信号确定拟合误差（S203）。最后根据拟合误差和更新预失真系数后输出信号的邻频泄露比调整设定阈值（S204）。在上述技术方案中，采集预失真处理后的信号进行阈值判断，在确定采集的信号满足设定阈值时，使用采集的信号更新预失真系数和调整设定阈值，故使用调整后的设定阈值对下一次采集的预失真处理后的信号进行阈值判断更能反映非线性失真的特性，从而提升预失真处理性能。

In method, by means of scientific management of the data exploration process, the repeatability of the data exploration process is ensured, and real-time invoking, sharing and multiplexing of the operations and the method of the data exploration process are ensured.
