An efficient peak frequency estimator for product high-order ambiguity function
In this paper, we consider improvement of parameter estimation accuracy of multicomponent polynomial-phase signals (mc-PPSs) using the product high-order ambiguity function (PHAF)...

Multi-microphone maximum a posteriori fundamental frequency estimation in the cepstral domain
In this work we derive a new cepstrum based maximum likelihood fundamental frequency estimator that exploits the information of multiple microphones. The new approach results in a...
