The Time-Hopping Pulse Position Modulation (TH-PPM) is one of the most popular approaches for IR-UWB multi-user systems, and a lot of research efforts have been devoted on its performance analysis. In several latest literature, a method of numerical computation of MAI characteristic function was carried out to derive precision analytical error performance, which, however, still showed a few inconvenient limitation on the system configuration. To overcome this shortage, the corresponding MAI model is enhanced in this paper, and the multi-access BER performance expression is alsoderived based on this modified model. Finally, Monte-Carlo simulations are carried out to verify the analytical results.
