Signal reconstruction from signed Fourier transform magnitude
TLDR
In this article, it was shown that a one-dimensional or multidimensional sequence is uniquely specified under mild restrictions by its signed Fourier transform magnitude (magnitude and 1 bit of phase information).Abstract:
In this paper, we show that a one-dimensional or multidimensional sequence is uniquely specified under mild restrictions by its signed Fourier transform magnitude (magnitude and 1 bit of phase information). In addition, we develop a numerical algorithm to reconstruct a one-dimensional or multidimensional sequence from its Fourier transform magnitude. Reconstruction examples obtained using this algorithm are also provided.read more

On the usefulness of STFT phase spectrum in human listening tests
Kuldip K. Paliwal,Leigh Alsteris +1 more
TL;DR: It is shown in this paper that even for small window durations, the phase spectrum can contribute to speech intelligibility as much as the magnitude spectrum if the analysis–modification–synthesis parameters are properly selected.

Real-Time Signal Estimation From Modified Short-Time Fourier Transform Magnitude Spectra
TL;DR: An algorithm for estimating signals from short-time magnitude spectra is introduced offering a significant improvement in quality and efficiency over current methods, and is applied to audio time-scale and pitch modification and compared to classical algorithms for these tasks on a variety of signal types.

The reconstruction of a multidimensional sequence from the phase or magnitude of its Fourier transform
TL;DR: In this article, the phase or magnitude information alone is not sufficient, in general, to uniquely specify a sequence, however, a large class of sequences are shown to be recoverable from their phases or magnitudes.

Signal reconstruction from phase or magnitude
TL;DR: In this article, a set of conditions under which a sequence is uniquely specified by the phase or samples of the phase of its Fourier transform was developed. But these conditions are distinctly different from the minimum or maximum phase conditions, and are applicable to both one-dimensional and multidimensional sequences.

On the ambiguity of the image reconstruction problem
Yu. M. Bruck,L. G. Sodin +1 more
TL;DR: It is shown that the retrieval ambiguity represents a lesser problem in the two-dimensional case compared to the well-known problem of image reconstruction from its spectrum modulus.
