小波域高斯混合模型与中值滤波的混合图像去噪研究(Gaussianmixturemodelinwaveletdomainmedianfilteringandhybridimagedenoising)

Low-pass filters allow the low frequency components of an input signal to pass through while attenuating (reducing) high frequency components. Measurement noise fall into the high frequency range of the signal spectrum, while the underlying process signal usually lies towards the low frequency end. Thus filters that are used to remove noise from measurements are of the low-pass types. This program uses Chebyshev FIR low pass filter based on antenna theory approach to filter noise from human speech signal.

对于通行工程里的两种调制方式PAM和QAM进行了性能仿真，并对他们的性能进行了比较。有信噪比，误码率等重要参数比较。还有具体的文档说明。(For the passage of two works in the PAM and QAM modulation for the performance simulation, and their performance compared. There is signal to noise ratio, bit error rate and other important parameters. There are specific documentation.)

说明：  运行主函数qam.m，可得到调用理论误符号率曲线和仿真结果。仿真结果包括误符号率和误码率。(running qam.m main function will receive the symbols mistakenly called theoretical curve and simulation results. Simulation results include misuse of the symbol rate and bit error rate.)

用户界面（或接口）是指：人与机器（或程序）之间交互作用的工具和方法。如键盘、 鼠标、跟踪球、话筒都可成为与计算机交换信息的接口。 图形用户界面（Graphical User Interfaces ，GUI）则是由窗口、光标、按键、菜单、文 字说明等对象（Objects）构成的一个用户界面 (User interface (or interface) refers to: Human and machine (or process) the interaction between the tools and methods. Such as keyboard, mouse, track ball, microphone and computer can become the interface to exchange information. Graphical user interface (Graphical User Interfaces, GUI) is by the window, the cursor, buttons, menus, text and other objects (Objects) consisting of a user interface)
