摘要

研究了多分量非平稳信号的联合时频表示问题。介绍了多分量非平稳信号Wigner-Ville分布(WVD)中交叉项的掩蔽新技术。WVD的理想浓度在被考虑的信号类型去除交叉项的同时被实现。利用信号的时间和频率支持信息来实现这一目标。

Reduced interference Wigner-Ville time frequency representations using signal support information

The problem of joint time-frequency representation (TFR) of multicomponent non-stationary signals is considered. We introduce a new technique of masking cross-terms in the Wigner-Ville distribution (WVD) of multicomponent non-stationary signals. Ideal concentration of the WVD is achieved at the same time cross-terms are removed for the considered type of signals. Time and frequency support information of the signal is used to achieve this goal.
