Fundamental frequency estimation based on adaptive time-averaging Wigner-Ville distribution
Sam Kwong, W. Gang, Ou Yang Jing Zheng · 2003
A method for fundamental frequency estimation based on the Wigner-Ville distribution is presented. The influence of the cross-term in the traditional Wigner-Ville distribution is reduced through the time-averaging technique, with the time interval adaptive to the fundamental frequency. Experimental results using speech signals show that this method can achieve a fairly good estimation of the fundamental frequency.>
