Abstract :
In this paper we propose two schemes to mitigate multiuser interference (MUI) in Multi user UWB system. Both these schemes are Direct Sequence Code Division Multiple Access (DS-CDMA) based Orthogonal Frequency Division Multiplexing (OFDM) systems. We investigate performance of both the proposed schemes under different users with additive white Gaussian noise (AWGN) and fading channel. Also, performance of proposed scheme is compared with DS-UWB proposed in [1].
