The Ultra-wideband (UWB) spread spectrum technology provides a unique platform for (integrated) communication services spanning a wide range of bit rates (from few kbit/s up to hundreds Mbit/s). The acceptance of the UWB technology worldwide is mainly related to coexistence issues with other existing narrowband and wideband systems sharing the spectrum with UWB.
In this paper, we present a proposal for a "detect and avoid" (DAA) procedure that UWB devices would use to mitigate interference to indoor broadband wireless communications services and ensure that the appropriate protection criteria are met.
We analyze the performance of an UWB system when the proposed procedure is applied. We assess the UWB system throughput and the time actually available to UWB for transmitting. We analyze the dependence of the UWB system performance on the DAA procedure parameters and on the characteristics of the victim system.
