Although the accuracy is the major concern for range estimation, it is also important to have low-complexity algorithms that can be employed in real time. In this study, two low-complexity range estimation algorithms are proposed for UWB signals, which achieve improved performance compared to the state-of-the-art low-complexity ranging algorithms. The proposed algorithms are inspired from two well-known algorithms; 'serial backward search' (SBS) and 'jump back and search forward' (JBSF). Performances of the proposed algorithms are compared with those of the SBS and JBSF algorithms based on real measurements. In addition, theoretical bounds are calculated in order to quantify the statistical performance of the algorithms. © 2014 IEEE.EnglishCramér-Rao lower boundUltra-widebandWireless positioningAlgorithmsBroadband networksRange findersComplexity algorithmsHigh-time resolutionLower boundsRange estimationStatistical performanceUltra wide band systemsUltra-wideband signalUltra-wideband (UWB)Enhancements to threshold based range estimation for ultra-wideband systemsConference Paper10.1109/ICUWB.2014.6958941
