This paper presents a new approach in the detection, localization, and classification of frequency and amplitude changes in nonstationary signal waveforms using a variable window short-time Fourier Transform (STFT) known as ST in short and an Extended Complex Kalman Filter (CEKF). Unlike the fixed window STFT, the variable window Short-time Fourier(More)
