This folder has two files for the simulation of dc motor braking. please run the *.m file to run the *.mdl file(This folder has two files for the simulation of dc motor braking. please run the*.m file to run the*.mdl file)

matlab程序 打开摄像头的程序 yuv格式 程序很简单 (matlab program to open the camera program yuv format procedure is very simple)

根据频率的不同，设置不同的滤波器，包括低通、高通、带通等(Depending on the frequency set different filters, including low pass, high pass, band pass, etc.)

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)
