OFDM 技术具有频谱利用率高、成本低等特点，随着人们对通信数据化、宽带化、个人化和移动化的需求，OFDM 技术在固定无线接入领域和移动接入领域将越来越得到广泛的应用(OFDM technology has high spectrum efficiency, low cost, and communication data, broadband, personal and moving the OFDM technology will increasingly be in the field of fixed wireless access and mobile access a wide range of applications)

扩展卡尔曼滤波算法，用于异步电动机的转速估计，效果良好(ekf algrithm ,used for estimate the speed of asychronous motor)

Blackman window filter programs

Matlab codes for financial models

可以对任意实现频谱细化，函数的参数见函数自身说明(Spectrum can be achieved for any refinement, the function of the parameters see the description of the function itself)

说明：  基于MIMO-OFDM的通信系统仿真，带注释。(Communication system simulation based on MIMO-OFDM, with notes.)

采用中心旋转法来进行曲波变换，带有几个demos。方便的进行curvelet变换(Center of rotation method used to carry out curvelet transform, with a few demos. Convenient for curvelet transform)

In any power system, stability is always a important parameter. To check the stability of a synchronous generator which is connected with the grid is the power angle and freq need to know. With the help of this simulation model one can easily find Power angle and Freq.
