Ultra wide bandwidth (UWB) signals are commonly defined as signals that have a large relative bandwidth (bandwidth divided by the carrier frequency) or a large absolute bandwidth. Typical indoor environments contain multiple walls and obstacles consisting of different materials. The RF ultra wideband (UWB) system is a promising technology for indoor localisation owing to its high bandwidth that...
