In this paper we combine the main results obtained within the ULTRAWAVES project on two critical issues: the characterization of the UWB propagation channel and the assessment of the capacity of an UWB system operating in a typical office environment. Based on the experimental data collected through a wide measurement campaign in a typical European office environment, we evaluate the performance of a single UWB link in a realistic multipath environment using either binary pulse position or pulse amplitude modulation. These data are used to extract the SNR specification for a target bit error probability. Then we use it to evaluate the system outage probability with a novel semi-analytic approach also described in the paper. A realistic master-slave UWB network based on DS-CDMA is considered and its capacity is expressed in terms of the average number of users served with a required outage probability level. The proposed approach is quite flexible and allows us to easily include realistic path loss models, power control mechanism and intra system interference.

Abstract

In this paper we combine the main results obtained within the ULTRAWAVES project on two critical issues: the characterization of the UWB propagation channel and the assessment of the capacity of an UWB system operating in a typical office environment. Based on the experimental data collected through a wide measurement campaign in a typical European office environment, we evaluate the performance of a single UWB link in a realistic multipath environment using either binary pulse position or pulse amplitude modulation. These data are used to extract the SNR specification for a target bit error probability. Then we use it to evaluate the system outage probability with a novel semi-analytic approach also described in the paper. A realistic master-slave UWB network based on DS-CDMA is considered and its capacity is expressed in terms of the average number of users served with a required outage probability level. The proposed approach is quite flexible and allows us to easily include realistic path loss models, power control mechanism and intra system interference.
