In the method of the invention, a baseband signal is pre-processed to realize nonlinearity compensation. The pre-processing method comprises the following steps: the filter coefficient and the multinomial coefficient of the high power amplifier are extracted; corresponding gain is calculated for the amplitude value of each point input into the sequence of the baseband signal, and the phase compensation value is calculated according to the amplitude gain; the phase compensation value and the gain which are corresponding to each point are synthesized into re-gain, a pre-processing value pi is obtained, and pre-processing output sequence is formed; the pre-processing output sequence is output into the high power amplifier directly or through a inverse filter.

本发明方法是将基带信号进行预处理来实现抵偿非线性，预处理方法是：提取出高功率放大器的滤波器系数和多项式系数；对输入基带信号序列中的每一点的幅值计算对应的增益，根据幅度增益计算出相位补偿值；每一个点对应的相位补偿值与增益合成复增益，得到预处理值p i ，构成了预处理输出序列；将预处理输出序列直接或经过反向滤波器后输出到高功率放大器中。
