Abstract :
In this paper, multi-antenna Pre/Post-Rake transmission for ultra-wideband impulse radio (UWB-IR) system is considered. Multiple-input multiple-output (MIMO) technology that transmits and receives data with multiple transmission and reception antennas is attractive technique because MIMO technology can improve the throughput or reliability of the communications. However, there is a problem that the interstream interference occurs at each reception antenna because the information datas are transmitted from multiple transmission antennas at the same time and the same frequency. In this paper, the channel estimation scheme of multi-antenna Pre/Post-Rake transmission for UWB-IR system is proposed and its bit error rate (BER) performance is analyzed by computer simulation.
