COFDM diseñ o y simulacion

• Assume you are a R/D manager of a communication equipment company, you are going to develop an IP Switch (including hardware and hardware), how do you arrange this project? (hint: what is the system architecture?Which technologies you need? How do you arrange your team into co-work groups?)

说明：  用matlab绘制史密斯圆图，电子通信专业必备源码(Smith Chart in Matlab)

矩不变分割，分割效果明显，在Matlab下完美实现(Moment-segmentation, segmentation obviously perfect realization in Matlab)

设计一个60阶的滤波器，要求设计的滤波器0~π/8的幅度为1，在π/8~2π/8的幅度为1/2，在2π/8~4π/8的幅度响应为1/4，在4π/8~6π/8的幅度响应为1/6，在6π/8~π的响应为1/8，并且画出理想滤波器和设计得到的理想滤波器的幅度频率和响应进行比较(Design of a 60-order filter designed filter 0 ~~ π/8 the amplitude is 1, the π/8 ~ 2π/8 the amplitude is 1/2, 2π/8 ~ 4π/8 amplitude response is 1/4, 4π/8 ~ 6π/8 the amplitude response of 1/6, 6π/8 ~ π response of 1/8, and draw the ideal filters and design of an ideal filter amplitude frequency and response to compare)

基于MATLAB环境下各种常用的插值算法的代码 简单明了 便于初学者学习(Based on MATLAB environment variety of commonly used simple interpolation algorithm code easy for beginners to learn)

本函数用于估计随机效应面板空间自回归(panel SAR)模型( computes spatial lag model estimates for spatial panels )

求小波系数的程序，即快速有简单 (wavelet coefficients for the procedure, Quick is a simple !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! )

可以很好的实现车牌的定位（粗细定位）两步实现。(Can realize a good positioning plate (thickness positioning) two-step to achieve.)
