Abstract
The capacity of UWB enabled wireless personal area networks is analyzed in a dense multipath environment. The performances of UWB systems employing a direct-sequence multiple access scheme are evaluated in terms of link outage probability and average aggregate network throughput, considering a network topology based on a clustered structure, formed by a multitude of uncoordinated coexisting piconets. We study the dependence of the system performances on some critical design choices, such as the Rake receiver scheme, the mono-pulse characteristics of the transmitted UWB signals, the structure of the piconet frame, the traffic characteristics. Results are obtained by applying a semi-analytical estimate procedure, which accounts of the large and small scale fading phenomena for the UWB indoor propagation channel
