UWB propagation channel experimental measurement and analysis

In order to apply UWB technology to a communication system, channel measurement and analysis of UWB signals in the 3.1∼10.6 GHz frequency-band become necessary. This paper presents the propagation measurement results for the devices based on the Direct Sequence Ultra Wideband (DS-UWB) technology, which includes the open-space channel, emulated conditions for channels inside an aircraft, as well as measurements inside a large aircraft. The measurements and performance evaluations focus on the BER vs. power level, data-rate, coding parameter and range. The set of collected parameters from our experiment results may be used to develop realistic models for a range of UWB channel.
