MULTIPLE ANTENNA TRANSMISSION TECHNIQUE FOR UWB SYSTEM

Abstract

In this paper, the channel estimation in multi-band OFDM (MB-OFDM) ultra-wideband (UWB) based multipleantenna transmission systems is studied. For multiple antennas, each preamble designed by the Zadoff-Chu sequence satisfies the orthogonal property in the time domain. Therefore, the proposed preambles can improve the system performance and be applied to MB-OFDM specification in the case of more than two transmit antennas.
