Abstract

The speedy dissemination of digital consumer electronics devices within home and personal area causes increments of multimedia communication and advent of entertainment networking. This feature of communication requires high data-rate transmission. In order to meet the demand, in this paper, a high-speed MB-OFDM system, proposal of 802.15.3a standard for WPAN, employing layered space-time architecture is considered for possible WPAN applications. The MB-OFDM system with multiple antennas increases the transmission rate efficiently with low multiplication operations. With an emphasis on a preamble design for multi-channel separation, we address a channel estimation in MB-OFDM with MIMO antenna system. By properly designing each preamble for multiple antennas 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 two transmitting antennas.
