Abstract :
Ultra-Wideband (UWB) is a potential technology for the future high-speed wireless network. The multi-access performance of UWB system with high data rates is investigated in this paper. In particular, an existing Interference Suppressing Orthogonal Frequency Division Multiplexing (IS-OFDM) approach is modified, an OFDM UWB multi-access scheme based on successive interference cancellation in a two-user case is proposed. The simulation results show that the proposed scheme can be used to improve the symbol error performance for the uncoded OFDM-based UWB systems to a certain extent.
