Abstract :
Inter symbol interference (ISI) due to the dense multi-path nature of the UWB channel results in large performance degradation, the Rake receiver can effectively overcome the ISI problems, in this paper, the analytical BER expression for the UWB system using the Rake receiver in the multi-path channel is derived. Furthermore, the performance of A-Rake, P-Rake and S-Rake is evaluated for TH-UWB system and DS-UWB system. Finally, based on the simulation results, conclusions are drawn considering the performance and complexity issues for system design in the IEEE 802.15.3a UWB channel.
