1. The topic of special issue
Theories and Methods of Signal Processing in Fractional Fourier Domain

2. Introduction for special issue
With rapid development of modern signal and information technologies, more and more mathematical tools have been applied to resolve the problems encountered in modern society. Among them, the fractional Fourier domain signal and image processing methods, which includes the fractional Fourier transform (FRFT) linear canonical transform (LCT), and factional calculus (FC), have received much interests in various fields of science and engineering in recent years. The research results have proved them be one of the most powerful signal and image processing tools and  it has become as one of the hottest research topics not only in signal processing community, but also in various other research fields.
The diversity of parameters of these fractional transform methods brings some flexibility in some cases as well as some challenges and problems of their own. For example, how to choose suitable parameters for some specific problems, and the discretization algorithm cannot meet the requirements of many practical situations in terms of speed and accuracy. This special issue is intended to present and discuss the new developments associated with the fractional signal and image processing methods and tools. We will solicit high quality, original research articles as well as review articles focusing on the FRFT, LCT and FC with new theories and applications.
