摘要：

The enormous amount of multimedia data will be transmitted by various devices of the wireless personal area network, and this network environment will require very high transmission capacity. In this paper, we apply multiple antenna to MB-OFDM UWB system for high performance. With an emphasis on a preamble design for multi-channel separation, we address a channel estimation in MB-OFDM system with multiple antenna. By properly designing each preamble for multiple antenna to be orthogonal in time domain, the channel estimation can be applied to the MB-OFDM proposal for IEEE 802.15.3a standard in the case of more than 2 transmit antennas. By using the multiple antenna scheme and proposed channel estimation technique, the reliability and performance of MB-OFDM system can be improved.
