偏移线性正则变换(OLCT)为信号处理和光学中许多著名的线性积分变换（如傅里叶变换、分数傅里叶变换、线性正则变换）提供了一个更通用的框架。为了刻画信号与OLCT的同时定位性，我们将过去几十年在傅里叶变换域中研究较多的Nazarov不确定原理、Hardy不确定原理、Beurling不确定原理、对数不确定原理和熵不确定原理推广到广义的OLCT域。

英文摘要：
The offset linear canonical transform (OLCT) provides a more general framework for a number of well known linear integral transforms in signal processing and optics, such as Fourier transform, fractional Fourier transform, linear canonical transform. In this paper, to characterize simultaneous localization of a signal and its OLCT, we extend some different uncertainty principles (UPs), including Nazarov's UP, Hardy's UP, Beurling's UP, logarithmic UP and entropic UP, which have already been well studied in the Fourier transform domain over the last few decades, to the OLCT domain in a broader sense.
