An overview of Time-Frequency analysis theory in the pass and now is given in this paper. Based on the study of former achievements and by using the newest Time-Frequency analysis method, I have developed a lot of new theory on Local Wave Time-Frequency analysis method by means of theory analysis, numerical computation and experiment.
A core problem discussed in this paper is using Local Wave decomposition method and Hilbert spectrum to analyse nonlinear and non-stationary data. The key part of th...
