Abstract: A Modified Transmitted Reference(MTR) system based on the character of UWB quasistationary channel is proposed, in which only a reference pulse is transmitted with data pulse in a bit period. In no Inter/Intra Symbol Inference (ISI) and a signal user cases, the BER performance of MTR receiver is better than TR receiver with higher data speed. Compared with DTR, the MTR system decreases the complexity of system because of no differentially encoded data with basic performance consistency. The simulation is considered using Scholtz's monocycle pulse and IEEE802.15.3a channel.

Key words: communication, ultrawideband(UWB), transmitted reference(TR), differential transmitted reference (DTR), modified transmitted reference(MTR)
