摘要
现代数字信号处理方法众多,时频分析在此领域应用广泛并仍然具有发展潜力。介绍了数字信号处理的时频分析方法的发展,从短时傅里叶变换,到Wigner-Ville分布,小波变换,希尔伯特-黄变换,EEMD,分别论述了5种方法的原理以及优缺点。
There are many methods of modern digital signal processing, time-frequency analysis method is widely used in this area and still has the potential for development. This paper describes the development of time-frequency methods, from the short-time Fourier transform to the Wigner-ViIle distribution, wavelet transform, Hilbert - Huang transform, EEMD, discusses on the principle as well as the advantages and disadvantages of the five methods.
