Capacity analysis for a power controlled UWB indoor system

Ultra wideband (UWB) is a potential key technology for the development of future short-range indoor radio communication systems providing very high bit rates services, low power consumption and location capabilities. In this paper we provide a semi-analytic approach to evaluate the system outage probability for a master-slave network based on UWB direct sequence code division multiple access scheme. The proposed approach for system analysis is quite flexible and allows us to easily include realistic path loss models, power control and multiple access interference. The technique has been validated by comparing the semi-analytic data with those from classical Monte Carlo simulation and obtaining results in very good agreement. The UWB coverage-capacity tradeoff is also investigated.
