Bispectrum estimation and its application in analysis of heart sound signals
Ying He · Information technology newsletter · 2004
In the paper, the higher-order statistics methods were used to estimate the bispectrum of heart sound signals. The experimental results showed that, compared with conventional power spectrum methods, bispectrum analysis can reveal extra and more objective information. Bispectrum estimation is an applicable and effective tool for analyzing and processing heart sound signals.
