Abstract :
The time-hopping pulse position modulation (TH- PPM) is one of the most popular approaches for IR-UWB multiuser systems, and a lot of research efforts have been devoted on its performance analysis. In several latest literatures, a method of MAI modeling, as well as the numerical computation of the MAI characteristic function, had been carrid out to derive precision analytical bit error performance, which, however, still drops inconvenient limitation on UWB system configuration. To overcome this shortage, an enhancement on the above mentioned MAI model has been proposed in this paper. Based on this modified model, the multi-access BER performance expression for the coherent receiver of the TH-PPM UWB system has also been derived. Finally, Monte-Carlo simulations have been carried out to verify the analytical results.
