Abstract :
A new analytical method is introduced for the exact statistical modeling of multiple access interference (MAI), in time hopping pulse position modulation (TH-PPM) ultra wideband (UWB) systems. Based on this model the exact bit error rate (BER) is expressed in simple formulas. The proposed modeling of MAI considers complete asynchronism, and is also suitable for modeling the MAI components contributed by individual paths in channels with Poisson arrivals, based on the time variables.
