Abstract :
An approximation for the average error probability (AEP) of the pulse amplitude modulation (PAM) impulse radio ultra wide band (IR-UWB) systems in the presence of multi-user interference (MUI) is derived assuming that the spreading codes are fixed in time. The comparison of the proposed theoretical expression and the empirical result shows the accuracy of our approximation for both direct-sequence (DS) and Time-Hopping (TH) multiple access techniques. From this approximation, we deduce criterion that enable us to select the set of codes optimizing the performance in terms of the AEP.
