Signal estimation from modified short-time Fourier transform
@inproceedings{Griffin1983SignalEF, title={Signal estimation from modified short-time Fourier transform}, author={Daniel W. Griffin and Jae S. Lim}, booktitle={ICASSP}, year={1983} }
In this paper, we present an algorithm to estimate a signal from its modified short-time Fourier transform (STFT. [] Key Method Using this algorithm, we also develop an iterative algorithm to estimate a signal from its modified STFT magnitude. The iterative algorithm is shown to decrease, in each iteration, the mean squared error between the STFT magnitude of the estimated signal and the modified STFT magnitude. The major computation involved in the iterative algorithm is the discrete Fourier transform (DFT…
