  ABSTRACT: This paper investigates the generalized uncertainty principles of fractional Fourier transform (FRFT) for concentrated data in limited supports. The continuous and discrete generalized uncertainty relations, whose bounds are related to FRFT parameters and signal lengths, were derived in theory. These uncertainty principles disclose that the data in FRFT domains may havemuch higher concentration than that in traditional time-frequency domains, which will enrich the ensemble of generalized uncertainty principles.
