Abstract

Validity of the standard Gaussian approximation (SGA) for modeling multi user interference (MUI) in impulse radio ultra wide band (IR-UWB) systems which do not implement power control is investigated. Analysis focuses on the case of UWB systems adopting binary pulse position modulation (2PPM) with a time hopping (TH) code division multiple access scheme. Theoretical predictions are compared vs. simulation outputs in order to quantify limitations of the SGA hypothesis.
