MPSK_QAM

Speed sensorless control of 3-phase induction motor using MRAS speed estimato

说明：  matlab编程最好的入门教程，相当清晰，推荐学习！(The best entry-matlab programming tutorials, very clear recommendation to learn!)

这是一个关于MATLAB环境下实现解调信号检错的程序(This is a MATLAB environment to achieve the demodulated signal error detection procedures)

Spectra is made using simple mathematics

说明：  画二维和三维箭头矢量，matlab工具包。直接调用。 This functin is used to draw 2D、3D-arrows. The size of arrow head is decided by the minimum distance between start and stop.(Two-dimensional and three-dimensional vector drawing arrows, matlab toolkit. Direct calls. This functin is used to draw 2D, 3D-arrows. The size of arrow head is decided by the minimum distance between start and stop.)

matlab关于灯光显示效果与背面灯光效果的程序(Matlab on the lighting effects, lighting effects and the reverse procedure)

在快速傅里叶变换大的基础上以对信号进行短时分析，能画出三维瀑布图。(In the fast Fourier transform big on the basis of the signal is short analysis, can draw 3 d waterfall diagram )

自编的倒频谱代码。倒频谱（信号）是信号频谱取对数的傅立叶变换后的新频谱（信号），有时候会称频谱的倒频谱(A cepstrum is the result of taking the Inverse Fourier transform (IFT) of the logarithm of the estimated spectrum of a signal)

船舶AIS轨迹提取，作出船舶AIS轨迹图。在此基础上，实现基于空间相似距离的K均值轨迹聚类。算法可以自定义轨迹聚类初始轨迹或者由程序随机生成初始轨迹，采用迭代的方法直到确定最终的聚类中心。(The extraction of ship AIS trajectory, make ship AIS trajectories. On this basis, to achieve similar K mean trajectory clustering based on distance space. You can customize the initial trajectory trajectory clustering algorithm or randomly generated by the program initial trajectory, iterative method was used to determine the cluster center until the end. )

采用matlab来计算数据矩阵的马氏距离，里面有word关于马氏距离的介绍(Using matlab to calculate the data matrix of the Mahalanobis distance, which has the word on the introduction of Mahal)
