本代码能实现拉格朗日函数拟合，经验证具有很好的插值拟合效果。(This code can achieve the Lagrangian function fitting, interpolation proven with good fitting effect.)

Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects. This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts: 1)Analog imperfection compensation for the direct upconversion transmitter 2)Design a DPD based on a memory polynomial predistorter 3)Performance evaluation via a number of parameters such as:EVM,PSD,SNR,

It is a simple demo for belief propagation algorithm.
