Theory and methods for sampling in fractional domains

摘要

The fractional Fourier transform (FRFT) and linear canonical transform (LCT) have been shown to be one of powerful tools in signal processing community. While sampling is a fundamental and core topic in the field of signal processing. The research of sampling theory and methods in FRFT and LCT domains received much interests in recent years. In this paper, we review the developments and research trends of sampling theories and methods associate with FRFT and LCT.
