Direction of arrival (DOA) estimation is a crucially important task of signal processing for audio applications. Infrasound might form Lamb or acoustic gravity waves and accordingly propagate at a speed that is different from the general speed. Therefore, conventional DOA methods that require a pres…
With rising demand for sensor networks in recent years, microelectromechanical systems (MEMS) sensors are growing more attractive because they are tiny and available at increasingly lower cost. A data sample detected using a MEMS sensor is, in general, stored temporarily in a register of the sensor…
A method is proposed for estimating the source signal and its direction of arrival (DOA) in this paper. It is based on ML estimation of the transfer function between microphones combined with the EM algorithm for a Gaussian Mixture Model (GMM), assuming that the signal is captured at each microphone…
