Abstract :
This paper has investigated the effects of jamming on UWB system and proposed a jam-resistant UWB-OFDM system (AJ-OFDM). We analyze the performance of the system in both single-user and multi-user and examine the jamming resistance of the system. The simulation results show that spreading the transmitted bit streams and interleaving the spread symbols would provide more robustness to jamming to that of IS-OFDM system as well as the conventional UWB-OFDM system.
