通信系统基于matlab的单边带SSB调制(Communications system is based on the single sideband SSB modulation matlab)

matlab code for digital signal processing

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)

matlab 可视化 微分方程 算法 超越方程 科学计算(matlab algorithm visualization differential equations beyond scientific computing)

异步电机矢量控制,有说明可以，照着做就可以了。有助于学习矢量控制。(Induction motor vector control, described could照着做it. Vector control contribute to learning.)

人工地震波生成程序 可根据输入的设计谱，来生成人工地震波，为matlab程序，应用方便(Artificial seismic waves generated program according to the design of the input spectrum afterlife waves adult site, matlab program, easy application)

空时信号处理过程中，信杂噪比计算的matlab程序(Space-time signal processing, noise ratio SNR calculation matlab program)

说明：  相场模型的经典教程，包含MATLAB源代码说明，适合新手(the classic tutorial of Phase field modeling , including Matlab source code description, suitable for junior programmer)

This recreation makes the filters more stable. For high sampling rates the time records are downsampled. For the low sampling rates the time records are upsampled. Depending on the Filter types. Iterative resampling is used in the Nth octave band time filter to improve the attenuation of the resample program. Also the filters are settled by preappending time data, then deleting the preappended data after filtering.

画ROC曲线,并求取相应的pf,pd值，求AUC值的matlab代码(Draw the ROC curve, and solve the PD, PF values)
