Abstract
Ultra wideband (UWB) technologies have been developed to exploit a new spectrum resource in substance and to realize ultra-high-speed communication and high precision telelocation. However, the interference effects have not fully been studied from UWB wireless systems to conventional narrow-band wireless systems sharing the same frequency bands. This paper experimentally evaluated the interference from two kinds of UWB sources, namely an impulse radio UWB a sources and direct-sequence spread-spectrum UWB sources, to 2-GHz digital transmission. Bit error rate degradation caused by the UWB sources were measured. It was found that in both cases the bit error rate had floor characteristics when the relatively-strong UWB sources interfered.
