2D FDTD Simulation program implemented in MATLAB

matlab 傅里叶变换 求包络 等对声音的处理文件(the matlab Fourier transform seeking envelope of sound processing files)

说明：  模式识别中人连识别眼镜定位，用的是matlab支持向量机开发的(human pattern recognition to identify even glasses positioning, using the Matlab SVM Development)

最小二乘法展開速度快的相位展開,很好的相位展開法(Least mean square method phase unwrapping)

说明：  针对CDMA2000标准的3G网络的一种简单仿真，采用matlab工具(Standard for CDMA2000 3G networks a simple simulation using matlab tools)

本程序按照胡广书《现代数字信号处理》书中的谱估计的内容仿真了各种经典谱估计方法以及现代谱估计方法（周期图法、BT法、welch法、自相关法、修正的协方差法、burg法），因为是课程作业，因此逻辑上写得十分简洁，适合初学者参考。(The program in accordance with the Hu-book of modern digital signal processing book spectral estimation simulation the various classical spectrum estimation methods, as well as the modern spectral estimation methods (periodogram, BT France, welch method, auto-correlation method, the modified covariance method , burg method), because the course work, so logically written very simple for beginners.)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

智能天线MVDR算法，自适应检测DOA，达到优化性能的目的。(The smart antenna MVDR algorithm, adaptive detection DOA, to achieve the purpose of optimizing performance.)

说明：  使用matlab实现贝叶斯向量自回归模型，可用于经济学中的预测(It can realize Bayesian vector autoregressive model, and it can be used to predict in economics.)
