关于ofdm的相关文章，都比较经典，适合ofdm开发者学习(On ofdm related articles, are more classic, suitable for developers to learn ofdm)

主要针对 MIMO中的alamouti 进行仿真测试，有2发1收，3发1收，4发1收 进行比较。(Mainly for the alamouti MIMO simulation test, there are two hair a close, 3 rounds a close, four made a close comparison.)

说明：  利用害明滤波器对白噪声信号进行加权,提高信噪比(Filter with the use of harm-ming weighted noise signal to improve signal to noise ratio)

3D HOG算法，需要引用库文件ffmpeg、boost等。(3D HOG ffmpeg、boost LIB)

用于描述图形周围GVF力场分布图，必须有前置的GVF源码，这个代码才能发挥作用(GVF force field used to describe the graphics around the map, must have front of the GVF source, this code can play a role)

程序来自《现代通信系统－使用matlab》英文版 已经调通！并加上了注释。 希望对大家有帮助1(fpga)
