Provides a methodology for characterizing a nonlinear RF Blockset™ power amplifier (PA) with memory and an adaptive DPD feedback system to reduce the output signal distortion of an RF transmitter. The initial step in the procedure determines the系数矩阵required by the RF Power Amplifier block when selecting the Volterra memory polynomial model with cross-terms [ 1 ].此步骤使用PA的实际测量数据。在得出PA模型的系数集后，执行了系统级模拟。该系统包括一种自适应DPD算法，可以在模拟过程中使用切换开关启用该算法，并演示RF发送器系统输出信号的线性如何在启用DPD校正后改善。
