A Survey on Blind Source Separation of Machine Fault Source in Time-frequency Domain
Xiao Yao-xian · Machine Tool & Hydraulics · 2011
The machine fault blind source separation method in time-frequency domain,which was named TF-BSS,was introduced.Its state of the art of current research was reviewed.The three typical algorithms,namely Cohen blind source separation,fractional Fourier transform blind source separation and empirical mode decomposition blind source separation,were discussed.Its further research problems were put forward.
