On the performance of multiuser multiband DSUWB system for IEEE 802.15.3a channel with hybrid PIC rake receiver

In this paper, we study the performance of multiband Direct Sequence Ultra Wideband (DS-UWB) system in multiuser environment for IEEE 802.15.3a channel. The receiver employs hybrid Parallel Interference Cancellation (PIC) technique with Selective Rake (S Rake) and Partial Rake (P Rake) receivers. The system performance is also evaluated for multistage PIC. The system is simulated for three different scenarios of IEEE 802.15.3a channel. The simulation results show that hybrid multistage PIC with S Rake receiver performs better than single stage Rake receiver (S Rake and P Rake) and multistage P Rake receiver, for all three cases of the channel.
