Hi this code for Video Denoising using sparse transformation. simply add the video u can see the difference. it working fine. tested.

基于最小均方误差准则的自适应数字波束形成器(Criteria based on minimum mean square error of adaptive digital beamformer)

演示如何使用活动场景转换的转换，从一个活动到另一个。使用moveImage和changeBounds的组合很好地转换图像的网格，一个活动的大图像和详细信息文本(Demonstrates how to the use Activity scene transitions when transitions one Activity to another. Uses a combination of moveImage and changeBounds to nicely transition a grid of images to an Activity with a large image and detail text.)

对已给定生成矩阵的卷积编码进行Viterbi解码，输出解码结果，留存路径以及度量(Have been given generator matrix Viterbi convolutional coding output a decoded result, and retained path metric)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)

时变通信系统的仿真，使两个例子的代码其所选信道为全同获平信道(Time-varying communication system simulation, so that two examples of the code of its selected channel with the agreed level for the whole channel)

2D image analysis & compression

MATLAB与串口的连接的GUI和M文件，很适用的。参照这个设计思路，可以跟句自己的需要进行修改和完善！(MATLAB GUI with the serial connection and M files, it is applicable. Reference to the design ideas, with the sentences to their own needs can be modified and improved!)

光伏电池simulink仿真模型，光伏电池IV和PV特性(Simulink simulation model of the photovoltaic cells, photovoltaic cells IV and PV characteristics)

说明：  讲述了凸优化的基本理论，包括定义，模型，鲁棒特性以及对信号重构的指导等。(Describes the basic theory of convex optimization, including definitions, models, robust features and guidance on the signal reconstruction.)
