In this letter we extend the use of interference suppressing (IS) OFDM UWB system from single user to multiuser scenarios. Multiple access capabilities are obtained by employing Multi-Carrier (MC) CDMA in the transmitter along with MMSE multiuser receivers. We illustrate the performance of the multiuser IS-OFDM UWB system with numerical results obtained from simulations.
