OFDMA_mapping

说明：  非常好用的程序，里面包括EMD分解和HHT谱分析的程序，可以很好地处理非线性数据(Very useful procedure, which include EMD and HHT spectrum decomposition process, can well handle nonlinear data)

通过对二维码的3个顶点定位，扫描从而确定二维码的位置为后续解码做准备(hrough the three vertices of qr code, scan to determine the location of the qr code in preparation for the subsequent decoding )

讨论HHT代码的精华，讨论HHT代码的精华(the description and solution of hht)

用proteus仿真实现逆变器，基本实现闭环控制，单片机是ATMEGA88。(The inverters are simulated by proteus, and the closed-loop control is basically realized. The single chip computer is ATMEGA88.)

《MATLAB仿真在现代通信中的应用》（徐明远）的随书光盘，里面附有全书的源码，很详细，很实用(" MATLAB simulation applications in modern communications" ( Xu Mingyuan ) of the book with CD-ROM, which attached to the source code, very detailed, very practical)

进行时延估计 包含双谱和互相关两种方法 没有高阶累积量(For time delay estimation contains double spectrum and cross-correlation two ways No higher order cumulants )
