线性调频信号的部分功能 线性调频信号的部分功能(range_migration range_migration)

蒙特卡洛源程序，可以运行，图像还不错的。值得一看。(Monte Carlo source, can run pretty good picture. Worth a visit.)

Does the graph of the reflectance and transmittance for the number N layers of the unidimensional photonic crystal. Reference: Fundamentals of Photonics-SecondEdition

采用bpsk调制的直扩通信系统的误码率仿真。可以直接运行，方便初学者使用。(BER modulation using bpsk DSSS communication system simulation. Can be directly run, easy for beginners to use.)

LT编码的顾波分布函数及其调用函数程序，好不容易编的，很有用啊(LT codes Gu wave function is called the distribution function and its application, finally compiled, useful ah)

some image matching and mosaic

这个函数得到一个形象的名字，应该是RGB，加载它并创建一个。与透明色的RGB图像的PNG地方是白色的。 如果第三个参数是setted黑色的非透明区域的功能将颜色(This functions gets an image name which should be RGB, load it and create a .png with transparent color where the RGB image is white. If the third parameter is setted the function will color in black the non-transparent areas)
