画出每个IMF分量及最后一个剩余分量residual的图形 画出每个IMF分量及剩余分量residual的幅频曲线 用Hilbert变换直接求该信号的瞬时频率 计算HHT时频谱和边际谱(Draw each IMF component and the last one remaining residual component graphics draw each IMF component and the amplitude of the remaining component of the residual frequency curve directly seeking the instantaneous frequency of the signal with the Hilbert transform spectrum and marginal spectrum calculation HHT)

主要介绍matlab的相关内容 可以提供初学者自学用 (Introduces relevant content matlab beginners can provide self-learning)

《现代通信系统》Matlab源程序,一共10章的内容，好东西分享("modern communications systems" Matlab source, a total of 10 chapters, sharing the good things)

实现了一个复高斯信道，以及收和发端的相关矩阵(Implements a complex Gaussian channel, as well as the originator of the correlation matrix of received and)

ODFM系统的系列仿真代码，主要是信道衰减方面的，运行时有点慢，耐心等待哦(Series ODFM system simulation code, mainly channel attenuation areas, run-time a little slow, be patient Oh)

实现坐标系的逆变换，即将dq坐标转换为abc坐标(dq TO abc)

高阶谱分析,用于检测两个信号的延时情况,应用方面非常广泛，适用于阵列信号处理、雷达信号处理等.包含了TDEL文件和tdeb.m(Higher-order spectral analysis for the detection of two signals delay the case, the application is very widely used for array signal processing, radar signal processing. Contains TDEL files and tdeb.m)
