最小均方误差（MMSE）的算法，MIMO OFDM matlab仿真,ICA（主分量分析）算法和程序。( Minimum mean square error (MMSE) algorithm, MIMO OFDM matlab simulation, ICA (Principal Component Analysis) algorithm and procedures.)

说明：  用于实现常规AM调制的MATLAB源程序。(Matlab demonstration script for AM modulation. The message signal is+1 for 0 < t < t0/3,-2 for t0/3 < t < 2t0/3 and zero otherwise.)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

说明：  本程序展示了二维归一化互相关用于 &nbsp 模式匹配和目标跟踪。该程序提示用户选择感兴趣的（ROI）的区域和对同类目标进行跟踪的数目。归一化交叉相关图表明，当值已超过设定的阈值时目标就已经确定。(This demo illustrates the use of 2-D normalized cross-correlation for pattern matching and target tracking. The demo prompts the user to select the Region of Interest (ROI) and the number of similar targets to be tracked. The normalized cross correlation plot shows that when the value has exceeded the set threshold, the target has been identified.)

Image Encryption based on the RGB PIXEL Transposition and Shuffling Abstract — Privacy is one of the key issues information Security addresses. Through encryption one can prevent a third party from understanding raw data during signal transmission. The encryption methods for enhancing the security of digital contents has gained high significance in the current era of breach of security and misuse of the confidential information intercepted and misused by the unauthorized parties. This paper sets out to contribute to the general body of knowledge in the area of cryptography application and by developing a cipher algorithm for image encryption of m*n size by shuffling the RGB pixel values. The algorithm ultimately makes it possible for encryption and decryption of the images based on the RGB pixel. The algorithm was implemented using MATLAB.
