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。
