Estimated performance of UWB impulse radio transmission including dirty RF effects

For studying the performance of an ultra-wideband (UWB) system, either measurements or simulations can be performed. Simulations for performance predictions are more flexible, but they require an accurate system modeling that takes into account the non-ideal hardware. This paper presents the UWB indoor channel modeling, including relevant, non-ideal hardware components for the UWB impulse radio technique. As a performance measure the estimated bit error rate versus distance and versus signal-to-noise ratio for Time Hopping Pulse Position Modulation (TH-PPM) in a line of sight indoor scenario is presented. The influence of the data rate on the bit error rate is investigated as well.
