matlab图形界面演示程序，适合初学，matlab GUI编程的朋友(Matlab GUI demo program, suitable for beginners, Matlab GUI Programming friends)

使用matlab检测图片中的物体，一幅图作为背景，另一幅图中在前一背景下新加了一个物体，则可通过此程序来检测到(Matlab object detection picture, a picture as the background, another picture of the previous context added a new object can be detected through this procedure to)

主要是QAM与16PSK频谱仿真、误码率比较仿真以及各自的星座图(Mainly QAM spectrum with 16PSK simulation, emulation, and error rate between the respective constellation)

ldpc编码，在加性高斯白噪声情况下描述出它的误码率随信噪比变化的情况(ldpc coding, in the additive white Gaussian noise cases, describe its bit error rate with signal to noise ratio the changes in the)

基于高斯过程的贝叶斯分类,详细介绍了高斯过程(Bayesian Classification With Gaussian Processes)

本程序可以实现二进制补码形式转换为原码形式(The program can complement binary form into the form of the original code)

NR潮流，主要应用于电力系统中。是一种基本的算法(NR powerflow, mainly used in power system.Is a basic algorithm)

IEEE 802.16d路径损耗模型属于对数正态阴影路径损耗模型。根据郊区宏蜂窝中发射机和接收机之间的障碍物密度，可以分为三种类型ABC。该代码利用MATLAB仿真了IEEE 802.16d路径损耗模型，并画出了未修正和修正的模型曲线以供对比参考。(IEEE 802.16d path loss models are lognormal shadow path loss model. According density suburban macrocell obstacle between transmitter and receiver can be divided into three types A B C. The code using MATLAB simulation of the IEEE 802.16d path loss model, and draw the uncorrected and corrected model curve for comparative reference.)
