摘要：

This paper discusses a raging technique of Ultra Wide-band (UWB) system. The Energy Detection (ED) and Matched Filter (MF) are common techniques as UWB pulse detection methods in TOA (Time of Arrival) ranging system. The two-step TOA estimation is combined the ED and the MY The two-step detection enables higher ranging accuracy than the ED with the simpler receiver structure than the MF. In this paper, the modified two-step estimation is investigated. A dual window and a sampling interval compensation technique axe proposed in the ED and the MF, respectively. The performances of MAE (Mean Absolute Error) are improved in the IEEE802.15.4a system.
