A novel singular value decomposition-based ultra wide band time-of-arrival estimation for multiple targets

It is widely <span>admitted that the estimation of ultra wide band (UWB) time-of-arrival (TOA) for multiple targets in indoor multipath channels a very challenging task. The existing algorithms deal with limited number and require complex exchange several messages. In this paper, novel TOA algorithm developed. proposed estimates first path (FP) without exchanging messages or using collision avoidance techniques. As step, singular value decomposition (SVD) employed to extract each target then matched filter, followed by an iterative threshold crossing algorithm, used determine corresponding FP TOAs. simulation results four targets, CM1 IEEE 802.15.4a channel model, showed can effectively detect estimate its TOA.</span>
