调频立体声接收机模型 对相应的立体声解码过程进行建模和仿真。设左右声道的信号分别为1000Hz和2000Hz的单频测试信号。 (FM stereo receiver model for the corresponding stereo decoding process modeling and simulation. Set left and right channel signals were 1000Hz and 2000Hz single frequency test signal.)

4qam，16qam，64qam在高斯信道下的误码率仿真程序(4qam, 16qam, 64qam under Gaussian channel BER simulation program)

此源码是我更改过的基于VFW(Video for Windows)的源码，使用了定时器能实时的显示图像，从网上可搜到原版源码，但是原版的功能是保存为一个文件，且不能实时显示，此版本虽然能显示，但感觉反应速度不是很快，没有基于DirectShow的程序更新速度快，不过在WM_PAINT消息处理里加while(1){capGrabFrame(ghWndCap) }刷新速度就快很多了，但是这样程序就进入死循环不能再处理其他消息，至于怎样改进，就靠读者你了。(This source is changed based on VFW (Video for Windows) source, using a timer to display real-time images from the Internet can be found to the original source, but original function is saved as a file, and can not be real-time display, Although this version can display, but feel the reaction rate is not fast, not based on DirectShow update speed, but in WM_PAINT message processing Riga while (1) {capGrabFrame (ghWndCap) } faster refresh rate on a lot, but this procedure to enter an infinite loop can not deal with other information, as to how to improve the reader to rely on you.)

INS和GPS基于位置速度的松组合程序，已经验证了，滤波收敛，程序中说明了如何选取滤波参数(INS/GPS integrated navigation ，Kalman filter，loosely integrated based on position and velocity)

视频质料 在matlab环境下创建的GUI的命令按钮的使用(Matlab video material in the GUI environment to create the command button to use)

说明：  一些matlab程序代码，在通信原理中实现一系列实验内容(Some matlab code, in communications to achieve some functional theory)

Spectrum estimation using periodogram smoothing

计算多变量的经验正交函数分解， 常用于海洋或气象的数据分析，简单易用。(Calculate multivariate empirical orthogonal function decomposition, commonly used in the ocean or meteorological data analysis.)

对正弦信号进行傅里叶变换，并对比不同的信号长度与采样频率对结果的影响(Fourier transform of the sinusoidal signal and contrast the different length of the signal with the sampling frequency results)

Estimates the power spectral densities (PSDs) using both the generalized Ridge Regression (GRR) method [Hoerl, Kennard] and the ordinary RR method with loading level decided by the harmonic mean (HKB) and a Bayesian estimator (LW) for deciding the diagonal loading level.
