dc.description.abstract | Ultra Wideband (UWB) is the promising candidate for
short-range high-speed wireless communication system. But, the UWB propagation characteristics, the fundamental resource for overall system design, have not fully analyzed yet. In this work, we investigated the UWB indoor propagation characteristics in office environments. So, we constructed the UWB channel measurement system using the frequency sweep method to measure the frequency responses on the 5GHz ~ 6.6GHz band. The measurements were performed in the 2 different offices, 34 receiver positions (20 positions are line-of-sight and 14 positions are non line-of-sight). From these measurement results, firstly, we modeled the path loss behavior of UWB signal. The path loss exponent and variance of log-distance law are suggested. Not only in case of full band, but also in case of each sub-band path loss parameters are analyzed. Then, the distributions of received signal powers are compared with the Gaussian distribution according to the receiver condition. Finally, for 9 receiver positions located in the corridor, the propagation characteristic difference between the case when a door is closed and the case when a door is opened is reported. The additional path loss and loss due to the door material and frequency selective characteristics are primarily analyzed. | en |
