摘要：
We consider a proper detection schemes for time hopping (TH)-ultra wide bandwidth (UWB) multiple access (MA) systems in multipath channel. First, we apply the well-known minimum mean square error (MMSE) multiuser detector (MUD). Next, we propose the improved detection scheme, which has a low complexity and can jointly estimate the channel parameter. Simulation results show that the proposed scheme shows a good performance with a low complexity and can estimate the channel parameter more correctly than the conventional scheme.(1).
