Abstract :
We consider the performance analysis of beam space-time of a multiple-input multiple output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems for high data rate wireless transmission. Employing multiple antennas at both the transmitter and receiver end offers a promising channel capacity, to facilitate the performance complexity tradeoff design in practice. This paper proposes the asymptotic capacity performance of Bezout WHT equalizers under i.i.d. AWGN and Rayleigh fading channels. Finally, we deploy our system with a high-data rate ultra multi-band OFDM (MB-OFDM) based wireless system for IEEE 802.15.3a.
