In this paper, the authors have considered the downlink multimedia transmission with Direct Sequence-Ultra WideBand (DS-UWB) communication system. They have evaluated performance of DS-UWB system under multiuser scenario. They have investigated performance of the system under synchronous and asynchronous transmission. They have discussed the effect of orthogonal and non-orthogonal code selection with effect of different UWB pulse selection. Also the performance of DSUWB with non-orthogonal code is compared with TH-PAM UWB. They have considered AWGN and UWB channel model for simulation.
