| Abstract(in English) | Ultra Wideband (UWB) radio, also called Impulse Radio, has recently been investigated for wireless communications, especially as a candidate for short range personal communications. TH-PPM (Pulse-Position-Modulation) UWB system can operate at low-level power, and provide high data rates and high capacity with promising quality in short range multipath environment. UWB signals, however, are spread over very large bandwidths and unavoidably overlap with existing narrow-band services. As a consequence, it is necessary to have a limitation on UWB transmitting powrer density as a rule to avoid interference. In hence, for UWB Ad-hoc networking, we usually need a short-range, multi-hop strategy to achieve low-level power communications. In this paper, we first focus on the need of relaying UWB signals. Then we propose a short range UWB system having a simple-structured UWB repeater, which can relay the UWB signal with a short controlled delay in the delay-critical communication environment. |
