时频分析工具箱
DL : 1
法国中央科学研究院和美国RICE大学共同开发了时频分析工具箱(matlab emd) 是一款非常好用的时频分析计算工具,它是分析时变非平稳信号的有力工具,matlab 时频分析工具箱提供了时间域与频率域的联合分布信息,清楚地描述了信号频率随时间变化的关系。 其中主要含有四种函数: 信号产生函数,可以产生不停类型的信号,如Chirp信号,bpsk信号等。 时频分析函数,可以计算线性、Cohen类、仿射类非线性分析值函数,例如短时傅里叶变换(STFT),Gabor变换,谱图,Wigner-Ville(WVD)等。 分析处理函数 图形显示函数,如等高线、三维图等。(Time-frequency analysis toolbox)
