BPSX150sCharacteristics

综合了主动学习和半监督学习的多项算法，很有价值的学习资料(Combination of active learning and a number of semi-supervised learning algorithm, learning valuable information)

simulink 实现了直接序列扩频通信系统，含详细模型图(simulink realization of the direct sequence spread spectrum communications systems, including a detailed model)

说明：  matlab教程,里面有许多有用的方法.(matlab tutorial, there are many useful ways.)

simulink 例程。电力电子课程用。参数已设置好。(The simulink routine. Power electronics courses. Parameters have been set up.)

附件中的m代码包括了一系列的拟合函数，这些函数通常的输入是概率分布的样本。还有最大似然估计仿真器、最小平方仿真器、混合高斯分布估计的EM算法、(M in the annex to the code, including a series of fitting function, which function normally is the probability distribution of input samples. There are maximum likelihood estimation simulator, emulator least squares, mixed-Gaussian distribution is estimated that the EM algorithm,)

说明：  摄像头采集，人脸识别 更改了matlab的simulink原例子，可以直接从usb摄像头实时采集图像，进行人脸识别。 (Camera capture, face the simulink matlab changed the original example, directly from the usb camera capture images in real time, for face recognition.)

THIS IS A MATLAB CODES TO SIMULATE 16 QAM Bit Error Rate for 16-QAM modulation using Gray modulation mapping

matlab 数字图像信号的频域分析及仿真 将二维数字图像进行傅立叶频域分析，并且做了图像幅度谱重建和相位谱重建，通过这个例子大家可以明白相位比振幅更重要。(matlab digital image signals in frequency domain analysis and simulation of two-dimensional digital image Fourier frequency domain analysis, and has done a reconstruction of the image amplitude spectrum and phase spectrum reconstruction, by this example we can understand the phase is more important than the amplitude.)

最大功率输出控制的光伏发电系统，通过输出功率作为反馈信号控制输入电压，是系统处于最大功率输出。这个是最大功率追踪部分。(Maximum power output of photovoltaic power generation system controlled by the output power control input voltage as a feedback signal, the system at the maximum power output. This is the maximum power point tracking section.)

说明：  matlab常用算法之一，MATLAB初学者可好好利用(One commonly used algorithm matlab, MATLAB beginner can make good use of)
