基于matlab光束传播法，自由空间中，光的传播-beam propagation method. calculate optical propagation in the free space.

本程序模拟光学图像的菲涅尔变换过程，近似模拟光学图像信息在自由空间传播过程中的衍射现象-This procedure simulated Fresnel transform process of optical image, approximate optical image diffraction phenomenon in the process of information transmission in free space

自由空间光通信中使用的双变量fox's H 函数，大家可以参考一下，，，，，(The bivariate fox's h function used in free space optical communication can be referred to as a reference)

自由空间中无线光通信系统使用OOK调制的误码率，源代码可直接运行(Bit error rate of free space optical communication system using ook modulation)
