直接序列扩频系统（DS，Direct Sequence）又称为直接序列调制系统或伪噪声系统（PN 系统），简称为直扩系统，是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱，在收信端，用相同的扩频友序列进行解扩，将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率，所以受调信号的频谱宽度将远大于要传送信息的频谱宽度，帮称之为扩频(Direct sequence spread spectrum (DS, Direct Sequence) modulation system, also known as direct sequence or pseudo-noise system (PN system), referred to as direct expansion systems, is currently the more widely used as a spread spectrum system. To send the information encoded by the pseudo-random sequence of carrier modulation. End of winter in the letter to extend the signal with the spreading sequence of spectrum, in the end prepared to receive and use the same sequence spread spectrum despreading friends, broadening the spectrum to restore the original signal expansion signals. Because the rate of pseudo-random sequence is much larger than the rate of information to be sent, so the frequency spectrum by adjusting the width of the spectrum is much larger than the width of the information to be sent to help is called spread spectrum)

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.)

由于信号在传播过程中，由于接收机的移动，就会产生多普勒频移，该文件先分析了多普勒滤波器的频响以及对多普勒频移进行了仿真(Due to the signal in the propagation process, due to the movement of the receiver, and will produce the Doppler shift, the file is first analyzed the frequency response of the Doppler filter and the Doppler shift the simulation)

本程序是智能算法：鱼群算法的函数和一个例子，在matlab10.0上经测试，可以完美运行(This program is a smart algorithm: a function and an example of the fish swarm algorithm has been tested and works perfect matlab10.0 on)

图像分析程序，他有效地实现了对输入图像的特征提取，并用MATLAB实现，它包括图像(Image analysis process, he effectively to achieve the input image feature extraction, and use MATLAB to achieve, which includes the image)

详细介绍了多种图像处理的案例，包括原代码！用于进行图像处理、分析、可视化和算法开发。可用其对有噪图像或退化图像进行去噪或还原、增强图像以获得更高清晰度、提取特征、分析形状和纹理以及对两个图像进行匹配。(Introduced a variety of image processing of cases, including the original code! Used for image processing, analysis, visualization, and algorithm development. Its noisy image can be used or degraded image denoising or restore, and enhance in order to obtain higher resolution images, extract features, analyze shapes and textures as well as the two images to match.)

Motion-Compensated Frame Interpolation (MCFI) is a technique used extensively for increasing the temporal frequency of a video sequence. In order to obtain a high quality interpolation, the motion field between frames must be wellestimated. However, many current techniques for determining the motion are prone to errors in occlusion regions, as well as regions with repetitive structure
