The impact of narrowband interference on the performance of UWB systems in the IEEE802.15.3a channel models

Ultra wideband (UWB) is considered to be one of the most promising short range wireless communication technologies; due to its high data rate, low cost and low energy consumption. Despite its enviable benefits, the performance of UWB systems may be degraded due to the presence of inband narrow band interference (NBI) signals and this performance must be carefully investigated. To this end; we provide a simple theoretical analysis to the bit error rate performance of the Rake reception of the UWB signal in the presence of NBI signal in the IEEE802.15.3a UWB channel models. The NBI signal is modeled as the standard IEEE802.11a, which is approximated as the sum of “N” tone interferers. We show that our analysis is coincident with the simulation results.
