An enormous amount of multimedia data will be trans-mitted by various devices connected to the wireless personal area network, and this network environment will require very high transmission capacity. In this letter, we apply multiple antennas to the MB-OFDM UWB system for high performance. With an emphasis on a preamble design for multi-channel separation, we address the channel estimation in the MB-OFDM system with multiple antennas. By properly designing each preamble so that the multiple antennas remain orthogonal in the time domain, the channel estimation can be applied to the MB-OFDM specification 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 the MB-OFDM system can be improved.
