QAM simulation using a carrier cosine wave with ISI

说明：  三相三线制并联型有源电力滤波器的设计与研究,一篇3万字左右的论文，还是不错的(Three-phase three-wire shunt active power filter design and research about a 30,000-word thesis, or good)

vehicle identification within a system.

说明：  这是一本关于matlab的教程，同时也是一本信号处理的教程，其特点是将matlab用于信号处理(This is a tutorial on matlab, but also a signal processing tutorial, and its characteristic is used in signal processing matlab)

由于小波及小波包技术可以将信号或图像分层次按小波基展开，所以可以根据图像信号的性质以及事先给定的图像处理要求确定到底要展开到哪一级为止，从而不仅能有效地控制计算量，满足实时处理的需要，而且可以方便地实现通常由子频带、层次编码技术实现的累进传输编码（即采取逐步浮现的方式传送多媒体图像）。这样一种工作方式在多媒体数据浏览、医学图片远程诊断时是非常必要的。另外，利用小波变换具有放大、缩小和平移的数学显微镜的功能，可以方便地产生各种分辨率的图像，从而适应于不同分辨率的图像I/O设备和不同传输速率的通信系统。相比之下，利用KL变换进行压缩编码，只能对整幅图像进行；而利用小波变换则能够比较精确地进行图像拼接，因此对较大的图像可以进行分块处理，然后再进行拼接。显然，这种处理方式为图像的并行处理提供了理论依据。 (As the little affected wavelet packet technology can signal or image stratified by wavelet and so on according to the nature of the image signal and the image processing requirements given in advance exactly sure on to what level, and so far not only can effectively control of calculation and meet the needs of the real-time process, and can be easily realized by sub-band usually coding technology, levels of the realization of the progressive transmission (that is, take gradually emerged coding the way multimedia image transfer). Such a way of working in multimedia data browse, medical image remote diagnosis is very necessary. In addition, by using wavelet transform has amplification, narrowing the mathematics of peace move microscope function can be easily produce all sorts of resolution image in order to adapt to different resolution in )

本程序实现神州飞船跟踪测控的计算机虚拟，动画中地球、飞船和地面12个测控站同时运动。本程序是有声动画的仿真，使用时只要把bhk_med.wav文件放在D盘里然后运行该程序就Okay了(The Shenzhou spacecraft tracking and control program to achieve a virtual computer, the animation of the Earth, spacecraft and 12 ground control stations at the same time exercise. This program is a sound animation of the simulation, when used as long as the bhk_med.wav file on the D drive in and then run the program on the Okay a)
