Indoor Localization Using Barely Perceptible Audio Signals

Indoor Localization Using Barely Perceptible Audio Signals

This paper presents a new approach to an audio-based indoor localization system. By using audio signals emitted by a public address sound system, mobile devices may globally localize themselves in an indoor environment where global navigation satellite systems are not viable or reliable. The use of...
