Dense frequency signal refers to the signal containing harmonic and interharmonic
components that are very close to each other in frequency domain. Due to the limited …

Aiming to solve the problem of dense-frequency signals in the power system caused by the
growing proportion of new energy, this paper proposes a dense-frequency signal-detection …

In power systems, dense frequency signals (DFSs) comprise several adjacent harmonics or
inter-harmonics derived from power electronic devices. Signals that contain two or more …

For the past few years, some authors have proposed several vibration analysis techniques
to detect the prosthetic femoral stem loosening, having found some differences in the …

Multiple signal classification (MUSIC) algorithm has been employed for many applications of
frequency estimation, emitter localization, direction-of-arrival (DOA) estimation, etc …
