Weighted Combined Envelope Spectrum

Weighted combined envelope spectrum (WCES) is proposed from spectral coherence (SCoh) for enhanced bearing fault diagnosis. Both simulation and experiment have validated its superior bearing diagnostic performance than squared envelope spectrum (SES), enhanced envelope spectrum (EES), and improved envelope spectrum (IES).
