动态Gabor矩阵测量的相位恢复
Phase Retrieval from Matrix Measurements of Dynamical Gabor Systems
相位恢复是一类由无相位采样值恢复待估信号的问题.本文讨论的采样是由动态Gabor系统得到的.我们证明了关于动态Gabor测量矩阵可相位恢复的充分条件，并给出了C2和R3中的例子.
Phase retrieval is the problem of recovering the underlying signals, which can only get the phaseless measurements. In this paper, we focus on the case that the measurements come from a dynamical Gabor system. We obtain some sufficient conditions on the measurement matrix of a dynamical Gabor system for phase retrieval, and also give concrete applications on C2 and R3.
