摘要:
基于左边四元数线性正则变换的相关性态，本文建立左边四元数线性正则变换的不确定性原理。其表明四元数值的信号在时域和频域中方差的乘积具有下界，仅有二维的高斯信号能满足不确定性原理的等式。In this paper, based on the properties of the left-sided quaternionic linear canonical transform (QLCT), an uncertainty principle is established for the left-sided QLCT. It states that the product of the variances of quaternion-valued signals in the spatial and frequency domains has a lower bound and only a 2D Gaussian signal minimizes the uncertainty principle.
