提出了一种新的基于非线性函数分段线性逼近的行为建模方法。PWL模型是通过对投入产出特性进行阈值分解得到的。在数字预失真器的设计中，PWL模型比传统的多项式模型具有更好的建模稳定性和建模误差性能。
A new behavioral modeling approach based on the piece wise linear (PWL) approximation of nonlinear functions is presented. The PWL model is obtained using threshold decomposition of the input-output characteristics. The PWL model is proved to provide a better modeling stability and modeling error performance than conventional polynomial models specially in the design of digital predistorters.
