基于matlab彩色图像转灰度图的程序，详细请看附件。(Matlab color images based on gray level transfer process in detail see annex.)

介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型(Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model)

我从这里下载一个MATLAB文件来计算激光的模式，拉盖尔-高斯模式，但它不能正常工作。所以我说我自己的函数。这是很简单的功能，我希望它是有效的以及。我用它和后结果我得到了。(i download one matlab file from here to calculate the modes in laser, Laguerre-Gauss modes but it was not working properly. So i wrote my own function. It is pretty simple function, i hope it is efficient as well. i used it and post the result i got.)
