无人机航迹规划技术研究及发展趋势_胡中华

对每一行为一个离散信号的信号矩阵进行FFT，输出频域信号矩阵和采样频率(FFT of the signal matrix, and the output is the spectrum matrix and the sampled frequency)

基于simulink的QPSK通信仿真 基于simulink的QPSK通信仿真-simulink QPSK

滑模观测器模型，实现永磁同步电机反电动势的估算(Sliding mode observer model.)

external interrupt function

自从PADS 9.5发布以来，我一直在用这个版本，稳定性不错，最重要是支持对象的捕捉，非常方便，而且还支持中文菜单，遗憾的是中文菜单环境下有bug，只要在默认状况下修改零件标号，就会自动退出(Since 9.5 since its launch PADS, I have been use this version, the stability is good, the heaviest if support object capture, is very convenient, but also support the Chinese menu, it is a pity that environment has a bug with the Chinese menu, as long as in the default condition change parts label, will automatically exit)

用深度学习的方法识别数字，神经网络使用CNN，数据集mnist(Identification number)

基于systemview的一些通信系统仿真实例(Some the communication system simulation examples based on systemview)

MATLAB语音去噪，LMS算法，RLS算法(MATLAB speech denoising, LMS algorithm, RLS algorithm)

说明：  产生BPSK信号，使用能量检测求检测概率； 对信号和噪声进行非负矩阵分解实现信号增强，和信号压缩(BPSK signal is generated by this code and ED is used to detect and calculate the detection probability.Finally, NMF method is used to enhance the signal.)
