Journal of Pseudo-Differential Operators and Applications ( IF 0.9 ) Pub Date : 2021-03-12 , DOI: 10.1007/s11868-021-00403-0 A. Razghandi , R. Raisi Tousi
In this paper we consider conditions under which the property of being phase retrievable is invariant among a frame and its dual frames. We also investigate perturbation of phase retrievable frames. Finally, we obtain an explicit expression of tensor product dual frames which leads to reconstruction of a signal from magnitudes of frame coefficients.

使用张量积双帧解决相位检索问题
在本文中,我们考虑一帧及其双帧之间相位可恢复性不变的条件。我们还研究了相位可检索帧的扰动。最后,我们获得张量积双帧的显式表达式,该表达式导致根据帧系数的大小重构信号。
