The Research On The Application Of Multi-antenna Technique To UWB Communication Systems

In this paper, we introduce history and nowadays of the middle UWB communication system. The UWB channel model and effect of wireless communication adopting multi- antenna are researched. This study presents two novel MIMO-MB-OFDM systems based on the MB-OFDM-UWB physical layer standard. The simulation shows that system could be improved in CM1-CM4 channels. Finally, in the part of receiver, we improved on a blind receiver algorithm based on independent component analysis. It's adapted well to MIMO-OFDM system.
