In this study, we proposed a joint time-frequency distribution of suppressing cross-terms aiming at
cross-terms interference of Wigner-Ville distribution. According to the analyzed signal, the Wigner-Ville
distribution and Smooth Pseudo Wigner-Ville distribution can be obtained. Moreover, the prototype of timefrequency
distribution can be obtained by non-linear filter for Smooth Pseudo Wigner-Ville distribution. In this
way, the distributions the joint time-frequency distribution came to the result of the product of two. As a result,
the joint time-frequency distribution can suppress cross-terms effectively and keep high time-frequency
resolution. Finally, simulations and experiments prove the effectiveness of the proposed method.
Key words: Cross-terms, joint time-frequency distribution, non-linear filter, wigner-ville distribution, , ,
