Abstract

一种APD校正***及方法，易于实现。该***包括核心单元、增益调整单元、误差生成单元和训练单元，其中：核心单元，对***输入信号进行延时，得到N路不同延时的延时信号，其中一路延时信号作为前馈信号输出至误差生成单元，N为不小于1的整数；以及根据***输入信号、N路不同延时的延时信号和APD系数，得到功率放大器PA的输入信号，PA的输出信号中耦合出一部分作为反馈信号；增益调整单元，对反馈信号的增益进行调整，得到反馈调整信号，并输出反馈调整信号至误差生成单元；误差生成单元，生成前馈信号和反馈调整信号的误差信号，并输出误差信号至训练单元；训练单元，根据误差信号，确定APD系数，并输出APD系数至核心单元。
