The linear canonical transform (LCT) is a new signal processing tool developed inrecent years. As a unified and multi-parameter class of linear integral transform, LCThas its unique advantages in non-stationary signal processing. Although it is not verymuch known, its special cases are widely used in various fields, often under differentnames, such as the Fourier transform, fractional Fourier transform (FRFT), Fresneltransform, time scaling, and others. Therefore, understanding the LCT may help to gainmore ...
