Khazani, Abdullah Indoor Multipath Ranging Time-of-Arrival (ToA) Ultra-wideband (UWB) Link to publisher's homepage at http://www.myiem.org.my/ Ultra-wideband (UWB) radio is a new carrierless communication scheme using impulses and is a candidate technology for future communication and ranging applications. In this paper, we consider the problem of node localizing in ad-hoc networks, in which positioning algorithm only exploits the high precision ranging capabilities offered by UWB and does not rely on GPS. A Time-of-Arrival (ToA) based ranging scheme using UWB radio link is proposed. In this paper, the problem of ToA estimation in multipath channels, source of estimation error are discussed. Two-way ranging (TWR) scheme was used for network synchronisation. Results show that the accuracy enhancement depends on two principal factors: the strength of multipath components and the variance of non-line-of-sight (NLOS) delays, which it shows that DS-UWB is best suited for ranging, due to its larger bandwidth and its higher frequencies of operation. 2011-08-17T15:01:58Z 2011-08-17T15:01:58Z 2006-09 Article The Journal of the Institution of Engineers, Malaysia, vol. 67(3), 2006, pages 13-17 0126-513X http://myiem.org.my/content/iem_journal_2006-177.aspx http://hdl.handle.net/123456789/13559 en The Institution of Engineers, Malaysia
