基于svd-tls功率谱分析的方法 ，是现代谱估计的一种常用方法(svd-tls-based power spectral analysis method is a kind of modern spectral estimation methods commonly used)

仿真了DSB信号产生和调制的过程，方法简单，内容详尽，已经过调试。(Simulation of the DSB signal and modulation process, the method is simple, detailed, has been testing.)

功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)

tsp matlab 旅行售货员问题的经典程序 很好的 望高手大侠多多几点(tsp matlab traveling salesman problem is the classic procedure lots of good looking master a few heroes)

二阶粒子群，比pso更加精确更加灵敏地优化函数。在标准pso算法中，微粒的飞行速度仅仅是微粒当前位置的函数，而二阶粒子群算法中微粒飞行速度的变化与微粒位置的变化有关(Second swarm, more sensitive and more accurate than pso optimize function. Pso algorithm in the standard, the particle particle flight speed is only a function of the current position, the second particle swarm flying speed of particles in the particle changes related to changes in the position)

最小均方误差（MMSE）的算法，包含位置式PID算法、积分分离式PID，是小学期课程设计的题目，仿真效率很高的，用于信号特征提取、信号消噪，大学数值分析算法，处理信号的时频分析，合成孔径雷达（SAR)目标成像仿真。( Minimum mean square error (MMSE) algorithm, It contains positional PID algorithm, integral separate PID, Is the topic of the elementary school stage curriculum design, High simulation efficiency, For feature extraction, signal de-noising, University of numerical analysis algorithms, When processing a signal frequency analysis, Synthetic Aperture Radar (SAR) imaging simulation target.)

说明：  通过训练jaffe数据库，实现识别人脸高兴、惊讶、恐惧、生气等六种表情，并圈出。可调用电脑摄像头实时监测。内附有使用说明，可以使用。仅供学习参考。(Through training Jaffe database, six kinds of facial expressions, such as happiness, surprise, fear and anger, are recognized and circled. Real-time monitoring with a computer camera can be invoked. With instructions for use, it can be used. For learning reference only.)

总结的混合粒子群算法、蚁群算法、遗传算法求TSP（旅行商问题）,值得看一看(Summary hybrid particle swarm optimization, ant colony algorithm, genetic algorithm for TSP (traveling salesman problem), it is worth a look)

应用Matlab采用Galerkin法求解偏微分方程(Galerkin method for solving partial differential equations by matlab)

audio signal processing and recognition,是一本台湾张智星教授所写的关于语音处理的书籍，网上有另一个版本书名叫《audio processing》，和这个有点区别，两个结合看效果会更好！(audio signal processing and recognition, is a book written by Professor Zhang Zhixing Taiwan books on speech processing, there is another version of the online book called "audio processing", and this little difference, the two combined to see better results!)
