Enhanced Orthogonal Matching Pursuit Algorithm and Its Application in Mechanical Equipment Fault Diagnosis

<div>Gear fault signal analysis results from the EOMP method: (a) waveform of the source signal and waveform of the reconstructed signal, (b) FFT spectrum of the source signal and FFT spectrum of the reconstructed signal, and (c) Hilbert spectrum of the source signal and Hilbert spectrum of the reconstructed signal.</div>
