Abstract
In this paper, we provide a novel analytical expression for the average BER in Impulse Radio Ultra Wide Band (IR UWB) networks affected by Multi User Interference (MUI). BER is evaluated based on the observation that interference in IR is provoked by collisions occurring between pulses belonging to different transmissions. The reference scenario consists of multiple asynchronous users transmitting IR-UWB signals using Pulse Position Modulation (PPM) in combination with Time Hopping (TH) coding. The proposed method requires specification of a similar set of system parameters as Gaussian-based approaches, but shows improved accuracy in estimating BER, in particular when sparse network topologies are taken into account. © 2005 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
