Abstract
In this correspondence, we define a discrete version of the angular Fo urier transform and present the properties of the transform that show it to be a rotation in time-frequency space, This new transform is a g eneralization of the DFT, Efficient algorithms for its computation can then be based on the FFT and the eigenstructure of the DFT.
