Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor, Hammurabi, used windmills for an ambitious irrigation project as early as the 17th century BC.

这是ofdm的毕设报告，里面有相应知识的学习最后还附加了ofdm的仿真，同时还有仿真图的分析(This is the complete set of ofdm report, which has the appropriate knowledge, learning and finally added ofdm simulation, as well as the analysis of simulation diagram)

反演工具箱，里面用到了三种反演方法。易于了解反演过程(inversion lsqr sqrt svd)

说明：  一款MATLAB航磁异常正反演以及常规处理软件。(A MATLAB aeromagnetic anomaly inversion and conventional processing software.)

Particle swarm optimization ...

We must handle non-linear skbs.

说明：  采用mtpa矢量控制方法对永磁同步电机进行转速控制，调速范围宽(pmsm mtpa controller)

说明：  MVDR算法的matlab语言实现，可以进行定向拾音和定向抑制(The realization of MVDR algorithm in MATLAB language can carry out directional pickup and directional suppression)

信号分析与处理，第一部分_序列的产生和序列的傅立叶变换，第二部分_序列的卷积，第三部分_FT时域卷积定理验证，(Signal processing analysis and application.)
