Abstract :
In this paper we present a multiuser multiband OFDM-based UWB system with interference mitigation capabilities. The proposed system combines the single band interference suppressing (IS) OFDM UWB system with time-frequency (TF) interleaving to enable symbol transmission in multiple bands along with multiaccess capabilities. Bit error rate (BER) performance of the proposed system is illustrated with numerical results obtained from simulations for various scenarios that include multiple users and narrowband interference.
