摘要
在移动通讯领域内,线性功率放大器的高线性度是保障通讯信息无失真传播的重要因素。本文基于前馈线性放大器的原理,利用数字自适应控制算法,实现了功率放大器的高线性度。实验数据表明这种方法取得良好的控制效果。
High linearity of the power amplifier (PA) is an important factor of the transmission without distortion in mobile communication systems. Based on the principle of the feed forward of linearization power amplifier and the adaptive digital control algorithm, realize high linearity of the PA is obtained. Experimental results show that the performance is good.
