摘要
We present an approach to designing discrete time-frequency distributions that are extremely localized in the time-frequency plane. These distributions, which satisfy the marginals, are constructed recursively by transferring energy among the points in the time-frequency distribution (TFD) in a direction which decreases the entropy of the TFD. This transfer is such that the resulting TFD continues to satisfy the marginal constraints.
