摘要

提出了一种自适应的Wigner-Ville分布干扰抑制方法。分析了Wigner-Ville分布中伪信号的结构，利用伪Wigner-Ville分布最优地掩盖了信号Wigner-Ville分布。由此产生的时频分布在表示质量方面优于Wigner-Ville分布，具有固定平滑窗口的伪Wigner-Ville分布以及修正B分布。

An automatic time-frequency procedure for interference suppression by exploiting their geometrical features

This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville distribution by the Pseudo Wigner-Ville distribution. The resulting time-frequency distribution outperforms in terms of representation quality the Wigner-Ville distribution, the Pseudo Wigner-Ville distribution with fixed smoothing windows, as well as the Modified B distribution.
