Detection And Avoidance Technique for Coexisting Pulse based UWB and OFDM system using Guard Interval

Abstract (in Japanese) (See Japanese page) 
(in English) Ultra Wideband (UWB) is an attractive technique that enable sharing spectrum with other radio systems to spread spectrum extremely wideband. However, there are potential interferences among those using in the same frequency bands and close range. This paper discusses the interference DAA (Detection And Avoidance) technique for coexisting pulse based UWB and OFDM systems. In a UWB transmitter-receiver, utilization of the OFDM signal is detected by correlating the GI (Guard Interval) signal, and the timing of GI period is also detected. The UWB signal is emitted during the GI period to mitigate the effect of interference to the OFDM signals from the UWB system. The DER (Detection Error Rate), FAR (False Alarm Rate) and BER (Bit Error Rate) performances are evaluated to show the availability of proposed DAA technique.
