Many signal processing algorithms for distributed sensors are capable of improving their performance if the positions of sensors are known. In this paper, we focus on estimators for inferring the relative geometry of distributed arrays and sources, i.e. the setup geometry up to a scaling factor. Firstly, we present the Maximum Likelihood estimator...
No PDF available ABSTRACT High mobility and an ability of gathering data from large terrains makes Unmanned Aerial Vehicles (UAVs) an excellent platform for placing visual or acoustic sensors. One recently emerging application of UAVs is search and rescue operation, during which drones are used to localize people in distress. A common approach to d...
Collaborative processing of signals recorded by distributed sensors brings about new opportunities as well as challenges to classical array signal processing. In this letter, we present a method for passive self-calibration of a distributed system in which each distributed node consists of an array of sensors. The proposed method estimates the posi...
Conference Paper
Enhancing speech from audio signals recorded using several microphones is of interest to many audio applications such as human-computer interfaces and teleconference systems. With an increasing availability of low-cost micro-electro-mechanical systems (MEMS) and powerful processing units, embedded systems are capable of recording and processing sev...
