Sound source localization (SSL) is an essential technique in many applications, such as robot audition, human-robot interaction and speech capturing. However, SSL from a binaural input is still a challenging problem, particularly when multiple sources are active simultaneously. In this work, we propose a multi-sources localization framework based on the time-delay compensation (TDC) estimator and...
In this paper we propose to use finite difference propagation methods to evaluate the wide band properties of the fast fading. For this purpose we adapted the MR-FDPF propagation model to simulate large bandwidth by combining numerous narrow band simulations. The results are compared with a channel sounder measurement campaign covering a bandwidth of up to 70 MHz. It is verified that fading characteristics...
According to research about real-time monitoring method and technology development of the ship piping leakage detection system, building theoretical models and analytical methods of typical leakage fault status in ship piping, solving pressure and flow signal analysis of locating the leakage and other key technologies. This article describes the basic principles of ship piping leakage detection system...
This letter introduces analytical expressions for the modeling of path loss and shadow fading in residential indoor-to-outdoor scenarios. The formulas have been calibrated using channel power measurements at the radio frequencies of common cellular systems and are thus suitable for channel modeling in femtocell networks. The expressions presented here can be used as a simple propagation model in system-level...
