This paper deals with the comparison of different multiple access techniques and different impulses in a multiple access communication systems based on Ultra Wide Band (UWB) impulse radio technology under non-ideal conditions. Several multiple access techniques and impulses have been designed and compared in the past, but mainly with the assumption of perfect synchronization of the users and perfect recovering of frame synchronization at the receiver. In this paper this unpractical assumptions are dropped. The results have been obtained by computer simulations. The sensitivity to synchronization errors of the Time Hopping PPM and the Direct Sequence multiple access techniques has been carried out with two different pulse shapes: the Gaussian monocycle and the Doublet. The impact of multiple access interference is also reported in the paper in order to have an exhaustive comparison of the UWB systems.

Abstract
This paper deals with the comparison of different multiple access techniques and different impulses in a multiple access communication systems based on Ultra Wide Band (UWB) impulse radio technology under non-ideal conditions. Several multiple access techniques and impulses have been designed and compared in the past, but mainly with the assumption of perfect synchronization of the users and perfect recovering of frame synchronization at the receiver. In this paper this unpractical assumptions are dropped. The results have been obtained by computer simulations. The sensitivity to synchronization errors of the Time Hopping PPM and the Direct Sequence multiple access techniques has been carried out with two different pulse shapes: the Gaussian monocycle and the Doublet. The impact of multiple access interference is also reported in the paper in order to have an exhaustive comparison of the UWB systems.File | Dimensione | Formato | |
