Abstract
In this paper, we evaluate the performances of direct-sequence pulse amplitude modulated and time-hopped pulse position modulated UWB systems based on Rake receiving. We provide an analytical expression for the average signal to interference plus noise ratio at the receiver output, which accounts of the processing gains introduced by the Rake with respect to interference and noise, as well as of propagation phenomena occurring in an UWB indoor propagation channel. Assuming that the UWB devices are organized in piconets, we investigate the impact on the link outage probability and average aggregate network throughput of some critical implementation choices, such as the UWB signal model, the mono-pulse characteristics of the transmitted UWB signal, the traffic conditions and the Rake receiver scheme.
