In this paper, a binary signal scheme is adopted based on two scenes of IEEE 802.15.3a Ultra-Wide Bandwidth(UWB) channel model. The average bit error rate formula Pe is deduced with added signal observation time window [0T] in the receiver. Two methods of adding window are presented. The simulation results show that both of two methods can get the suitable window [0T] to ensure the most channel characteristics are captured and system average bit error rate Pe is close to the theoretical value, while the signal observation time is reduced.
