摘要：
In this paper, we consider cross time-frequency distributions, with particular emphasis on their ability to preserve phase difference (between two signals) information as a function of time and frequency In addition, some properties of cross time-frequency distributions are examined and compared with the traditional Cohen's class of time-frequency distributions. Finally, the phase preserving properties of appropriately defined cross time-frequency distributions are illustrated with a pair of Gabor logons.
