Algorithmic Implementation of Multi-Window STFT Phase Retrieval
Ting Chen, Hanwen Lu, Wenchang Sun +1
STFT phase retrieval aims to reconstruct a signal from spectrogram magnitudes. While two compactly supported windows theoretically guarantee uniqueness, a complete algorithmic fram…

STFT Phase Retrieval with Two Window Functions
Ting Chen, Hanwen Lu, Wenchang Sun +1
In this paper, we consider the uniqueness of STFT phase retrieval with two window functions. We show that a complex-valued locally integrable nonseparable signal is uniquely determ…

Sampling Density for Gabor Phase Retrieval
Ting Chen, Hanwen Lu, Wenchang Sun
Gabor phase retrieval stands for recovering a square integrable function up to a global phase from absolute values of its Gabor transform. In this paper, we study Gabor phase retri…
