关于短时傅立叶变换的实验 其中有补0的相关分析 希望会对大家有帮助(On short-time Fourier transform of the experiment which fill 0 correlation analysis we hope will be helpful)

说明：   采用一种不完全的微分算法，被控对象为时滞系统。对象的输出端加的随机信号，幅值0.01.采样时间是20ms。(PID Controler with Partial differential)

频谱感知 能量检测算法 SNR -15 -20对比输出结果(energy detection spectrum sensing)

说明：  matpower电网潮流计算工具下载，功能强大(Mapower power grid power flow calculation tool download, powerful function)

说明：  利用延迟-相加法对波达方向进行估计，程序简明易懂，适用于初学者。(using delayed- add method to estimate DOA, easily understandable for beginners.)

频率估计问题一直是研究的热点。此为一个相位差法估计频率的程序代码，可供学习参考。(Frequency estimation has been the research focus. This is a phase difference method to estimate the frequency of the program code, for learning reference.)
