In this paper, we consider the problem of joint direction-of-arrival (DOA) and fundamental
frequency estimation. Joint estimation enables robust estimation of these parameters in multi …

In this paper, the problem of joint multi-pitch and direction-of-arrival (DOA) estimation for
multichannel harmonic sinusoidal signals is considered. A spatio-temporal matrix signal …

Reverberation is well-known to have a detrimental impact on many localization methods for
audio sources. We address this problem by imposing a model for the early reflections as …

In this article, we present a novel method for high-resolution joint direction-of-arrivals (DOA)
and multi-pitch estimation based on subspaces decomposed from a spatio-temporal data …

Time-difference-of-arrival (TDOA) estimation is an important problem in many microphone
signal processing applications. Traditionally, this problem is solved by using a cross …

In this paper, spatio-temporal filtering methods are proposed for estimating the direction-of-
arrival (DOA) and fundamental frequency of periodic signals, like those produced by the …

It is well-known that filtering methods can be used for processing of signals in both time and
space. This comprises, for example, fundamental frequency estimation and direction-of …

This paper presents an enhancement of a recently proposed method of joint pitch and
direction of arrival extraction for speaker localization. We propose a new pre-processing …

The harmonic model, ie, a sum of sinusoids having frequencies that are integer multiples of
the pitch, has been widely used for modeling of voiced speech. In microphone arrays, the …

Many natural signals, such as voiced speech and some musical instruments, are
approximately periodic over short intervals. These signals are often described in …
