Abstract: The non-orthogonal matrix precoding (NOM-p) is proposed to avoid signal-to-noise ratio dips in discrete-Fourier-transform spread (DFT-s) orthogonal frequency division multiplexing (OFDM) ...
Abstract: The information of gear fault features is contained in vibration signals with the form of periodic impulse. Traditional signal decomposition methods mostly are suitable for AM-FM signals.
