在时频二维域上表示信号从理论和实际上都有许多优点,本文概述了这方面的研究情况,从应用角度介绍了一种有效的表示方法——Wigner分布。指出了它比其他方法具有的优点以及有待进一步研究的问题。
Representing the signal in the two-dimensional domain over time and frequency has many advantages both theoretically and practically. In this paper, the research situation in this area is summarized and an effective representation method, Wigner distribution, is introduced from the application point of view. It points out the advantages it has over other methods and the problems to be further studied.
