Abstract:
In this paper we have considered the downlink multimedia transmission with Direct Sequence-Ultra wideband(DS-UWB) [1] communication system. We have evaluated performance of DS-UWB system under multiuser scenario. We have investigated performance of the system under synchronous and asynchronous transmission. We have discussed the effect of orthogonal and non-orthogonal code selection with effect of different UWB pulse selection. Also the performance of DS-UWB with non-orthogonal code is compared with TH-PAM UWB [2]. We have considered AWGN and UWB channel model for simulation.
