Power system dynamic frequency measurement based on novel interpolated STFT algorithm
As the product of time and frequency resolution of the Short-Time Fourier Transform (STFT) constant, the dynamic frequency measurement accuracy provided by the STFT is reduced under asynchronous sampling. This paper proposes a novel...

Toward High-Quality Real-Time Signal Reconstruction from STFT Magnitude
An efficient algorithm for real-time signal reconstruction from the magnitude of the short-time Fourier transform (STFT) is introduced. The proposed approach combines the strengths of two previously published algorithms: the Real-Time Phase ...

Performance Analysis of Convolutional Neural Networks with Different Window Functions for Automatic Modulation Classification
Fourier Transform (STFT) based signal spectrogram. By using ResNet18 and MobileNet cross-combined with FFT and STFT input data, the simulation shows that the STFT data provides a higher AMC accuracy than that of FFT data. ...

A study of parameters setting of the STADZT
the widely used Short-Time Fourier Transform (STFT). This paper describes the parameters overlap. Because STADZT is very similar to STFT, the paper includes a comparison of the spectral analysis of a nonstationary signal created by...
