QPSK modulation in Rayleigh channel

岭回归函数，基于SVD分解的岭回归函数，已经证明了是非的有用和强大( center input and output, so we can estimate w0 separately since we don t want to shrink w0 )

本文件包含三个matlab程序，包括线性调频Z变换的实现和应用。(This file contains three Matlab procedures, including the realization and application of chirp Z transform.)

JPDA的matlab程序 可以使用 效果不错(JPDA matlab )

2代小波示意程序，演示第二代提升小波算法实现，(secondwavelete)

Matlab 图形图像处理函数详细列表，包括各种MATLAB 图像处理命令。(Matlab graphic image processing function, a detailed list, including all MATLAB image processing commands.)

计算临界转速的小程序，考虑了轴的分布质量，但是不包括振型(Calculated critical speed of small programs, considering the quality of the axis of the distribution, but does not include the vibration mode)

本资料是用matlab模拟单色光衍射的GUI界面，操作方便，便于修改和改变参数(This information is a GUI interface using of matlab simulation monochromatic diffraction, easy to operate, easy to modify and change the parameters)

1、Rayleigh_Doppler_singlePath.m 产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法； 2、Rayleigh_Doppler_multiPath.m 根据多条径的延时和强度，产生频率选择性衰落； 在单径和多径两个程序中，均提供了其功率谱的输出代码； (1, Rayleigh_Doppler_singlePath.m Single Path Rayleigh fading generated using the six kinds of methods and compared recommend using the first six kinds of methods 2, Rayleigh_Doppler_multiPath.m Drive under a number of delay and intensity, resulting in frequency selective fading in single-track and multi-path two procedures, which provide the power spectrum of the output code )

说明：  供大家学习UWB的simulink建模仿真,希望大家多多交流(For everybody to learn the simulink modeling and simulation of UWB, hope more exchanges)
