Bispectrum and reconstruction of modulation signal extracted from ship-radiated noise
《Chinese Journal of Acoustics》1995年第1期1-10,共10页WU Guoqing and REN Rui (State Key Lab. of Acoustics,Institute of Acoustics. Academy Sinica, Beijing, 100080) 
The ship radiated noise is analyzed by higher-order spectra, which preserve the phase characteristics of signals. Phase information is suppressed in power spectrum and double fre quency power spectrum. Bispectrum an...
