Wigner-Ville distribution associated with the quaternion linear canonical transform and their generalized uncertainty principles
摘要
Wigner-Ville distribution (WVD) in the frame work of quaternion linear canonical transform (QLCT) (WVD-QLCT) is the generalized version of WVD in the quaternion algebra. Recently, some properties and applications in detection of linear frequency modulated (LFM) signals have been studied for the WVD-QLCT. In this paper, we first establish a relationship between WVD-QLCT and QFT and then we derive different uncertainty principles (UPs) which includes the Heisenberg’s UP, logarithmic UP, Hardy’s UP, Donoho Stark’s UP and Beurling’s UP associated with the WVD-QLCT.
