simulation of 4 ask this simulation need more improvement. I ll refine it later but it has the basic for a 4ask signalling scheme. it ll compare the result with analytical answer and depicts it in a semilog plot.

这是姜启源教授在清华大学讲解数学建模课程的资料，对于数学建模由入门到精通十分有用(lecture in math modeling,given by Professor JiangQiyuan )

是一种双隐层反向传播神经网络，窗函数法设计一个数字带通FIR滤波器，采用的是通用的平面波展开法。( Is a two hidden layer back propagation neural network, A window function design FIR digital band-pass filter, Using common plane wave expansion method.)

这是一个uwb用于体域网的信道仿真程序，可以进行仿真，它符合IEEE.802.15.4a，非常好！(This is a body area network for the uwb channel simulation program allows for simulation, it is consistent with IEEE.802.15.4a, very good!)

说明：  这个源代码文件包含了一个非常生动的杨氏干涉的模拟过程，其显示的结果是一个动画形式的(the source document contains a very vivid Young's interference in the simulation process. its display is the result of a form of animation)
