A Reduced Complexity Algorithm for Multi User Detection in DS UWB Systems

UWB is the latest technology to cause huge advances in wireless communication, networking, and radar and positioning systems. Many novel algorithms for the multiuser detection have been proposed for a DS-UWB multiuser communication system. In this paper we have proposed a reduced complexity Multi User detector based on minimum mean square error (MMSE).The algorithm exploit the inherent multipath diversity and also mitigate the effects of both inter symbol interference(ISI) and multiuser interference (MUI) with the reduced complexity. Simulation results show that the algorithm perform better than the other known detectors with the same complexity in literature
