AI中文摘要:

受二次相位积分变换在信号处理、光学和时频分析中广泛应用的启发,本文发展了一种新的积分变换,称为四元数二次相位Dunkl变换(QQPDT)。我们对其基本性质进行了详细研究。特别地,我们建立了连续性、线性性、缩放性、调制性、Riemann-Lebesgue结果、反演公式和Parseval恒等式。此外,我们为QQPDT建立了Heisenberg型和Donoho-Stark型不确定性原理。最后,我们开发了一种在QQPDT域中的信号恢复算法。所提出的方法能够在适当的局部化条件下,从部分观测中重建缺失的信号信息。

英文摘要:

Motivated by the wide applications of the quadratic phase integral transform in signal processing, optics, and time frequency analysis, in this paper we develop a new integral transform called the quaternion quadratic phase Dunkl transform (QQPDT). We present a detailed study of its fundamental properties. In particular, we establish continuity, linearity, scaling, modulation, Riemann Lebesgue result, inversion formula, and Parsevals identity. In addition, we estab lish Heisenberg and Donoho-Stark-type uncertainty principles for the QQPDT. Finally, we develop a signal recovery algorithm in the QQPDT domain. The proposed method enables the reconstruction of missing signal information from partial observations under suitable localization conditions.
