Abstract :
A general method for the evaluation of the symbol error probability (SER) of both M-PAM and M-PPM UWB systems, in presence of multipath channel, multiuser and strong narrowband interference is presented. This method is shown to be able to include all the principal multiaccess techniques proposed so far for UWB, like time hopping and direct sequence. A comparison between the performance of three of these techniques is also presented, for both ideal RAKE receiver and MMSE equalizer, in an indoor communications scenario.
