自己编写的fft变换的MATLAB源代码！里面还有操作过程。很好用哦(Have written MATLAB s fft transform the source code! There is also the process. Oh, well used)

说明：  ecg preprocessing baseline removal, powerline interferance removing

PMSM Motor control with DSP

MUSIC算法是最经典的超分辨DOA估计方法，它利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA。MUSIC算法对DOA的估计从理论上可以有任意高的分辨率(MUSIC algorithm is the most classical super-resolution DOA estimation method. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectral function, and detects the DOA of signal through peak search. MUSIC algorithm can theoretically estimate DOA with arbitrary high resolution.)

说明：  元学习算法的一种——IDBD算法，实现信道均衡仿真(IDBD, a meta-learning algorithm, realizes channel equalization simulation)

vector algebra extension to exterior product

Non-metric label propagation 的MATLAB 实现源码(the code of non-metric label propagation by matlab)

分别建立pid控制与模糊PID控制的BLDC仿真模型，对比效果良好(BLDC simulation models of PID control and fuzzy PID control are established respectively, and the comparison results are good.)

慢速跳频，调制样式为MFSK(MFSK/FH)，包括信号的发射接收模型，自己写的代码，仅供参考。(Slow frequency hopping, modulation pattern for the MFSK (MFSK/FH), including the launch of signal reception model, write your own code, for reference purposes only.)

本教程主要论述了如何设计IIR滤波器的详细细节(This tutorial focuses on how to design IIR filter for further details,)
