摘要

四元数线性正则变换（QLCT）框架中的Wigner-Ville分布（WVD-QLCT）是四元数代数中WVD的推广版本。近年来，人们对WVD-QLCT的一些特性及其在线性调频信号检测中的应用进行了研究。本文首先建立了WVD-QLCT与QFT之间的关系，然后推导出与WVD-QLCT相关的各种不确定性原理（UPs），包括Heisenberg UP、对数UP、Hardy UP、Donoho Stark UP和Beurling UP。

Wigner-Ville distribution associated with the quaternion linear canonical transform and their generalized uncertainty principles

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.
