Type: article
Abstract: . The IEEE 802.15.4a standard for impulse ra-dio ultrawide band (IR-UWB) communication systems de-fines a ranging scheme which relies on the measurement of the round-trip propagation time of electromagnetic pulses. Accuracy is strongly dependent on the estimation of the time-of-arrival (TOA) of the pulse that is spread in time due to multipath propagation. The major concern therefore is the proper detection of the leading edge. In this work, the rang-ing capabilities of the standard are analyzed for an energy detector receiver. Emphasis is put on the influence of trans-mitter and receiver parameters, which are evaluated for a set of measured scenarios. It is shown that sub-meter ranging accuracy can be achieved with fixed parameter settings.
