Abstract:The free metaplectic transformation (FMT) is an
‐dimensional linear canonical transform. This transform is much useful, especially in multidimensional signal processing and applications. In this paper, our aim is to achieve an efficient time‐frequency representation of higher‐dimensional nonstationary signals by introducing the novel free metaplectic wave packet transform (FM‐WPT) in
, based on the elegant convolution structure associated with the free metaplectic transforms. The FM‐WPT preserves the propert… Show more
