Python是一种计算机程序设计语言。是一种面向对象的动态类型语言，最初被设计用于编写自动化脚本(shell)，随着版本的不断更新和语言新功能的添加，越来越多被用于独立的、大型项目的开发。(Python is a computer programming language. As an object-oriented dynamic typed language, it was originally designed to write automated scripts (shells). With the updating of versions and the addition of new language functions, it is increasingly used in the development of independent, large-scale projects.)

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,
