Introduction-to-Programming

说明：  这是一篇关于多用户下行链路预编码的文章，主要是从一些基本的矩阵变换以及矩阵运算方面讲解一些原理，最后给出仿真实验

通信系统lte发展中慢（阴影）衰落仿真模型，只需要输入几个参数(Lte the development of communication system simulation model of slow fading, just enter a few parameters)

This file includes kalman filter and induction motor model

In this document we proposed a face recognition algorithm that enhance the recognition rate and reduce the complexity.

说明：  利用粒子群优化算法对支持向量机中的核函数参数和惩罚参数进行优化是非常有效的手段，可以大大提高鲁棒性。实际过程中读者可通过下载我上传的代码，简单进行修改和阅读附件论文即可快速掌握相关方面的知识，快速使用这一方法。(Particle swarm optimization (PSO) is a very effective method to optimize the kernel function parameters and penalty parameters of SVM, which can greatly improve the robustness. In the actual process, readers can quickly grasp relevant knowledge and use this method by downloading the code I uploaded, simply modifying and reading the attached paper.)

Harris角点提取实现了对棋盘格模板角点的精确提取，matlab程序及示例图片。(Harris Corner Detection realize the chessboard grid template Corner precise extraction, matlab procedures and sample images.)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.
