认知无线电 频谱检测技术 基于MATLAB的仿真(cognitive radio)

这是一个用matlab实现的人脸识别的pca方法，正确识别率不错。(err)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

认知无线电频谱检测技术的研究,有循环检测，周期性检测，仿真程序和结果。很全面。(Cognitive radio frequency spectrum detection technology, there are cycle detection, periodic testing, simulation program and results. Very comprehensive.)

使用simulink实现的msk方针 大家可以参考一下(Simulink realization of the use of the principle of msk we can refer to)

本文件详细描述了如何利用matlab去检测图片中含有的直线元素，利用hough变换。(This document describes in detail how to use matlab to detect images containing linear elements using hough transform.)

利用遗传算法求解75个城市之间的最优路径，得到的结果较为理想。(The use of genetic algorithm for optimal path between the 75 cities, the result is more desirable.)
