Abstract :
Ultra wideband (UWB) technologies have been developed to exploit a new spectrum resource in substances and to realize ultra-high-speed communication, high precision geolocation, and other applications. However, the interference effects had not previously been studied from UWB wireless systems to conventional narrowband wireless systems sharing the same frequency bands. This paper experimentally evaluates the interference from two kinds of UWB sources, namely a direct-sequence spread-spectrum UWB source and an impulse radio UWB source, to a 5- GHz digital transmission system. Statistical properties of the UWB sources and the average bit error rate degradation of the 5-GHz system are presented.
