Abstract :
Multiple transmit and receive antennas can be used with orthogonal frequency division multiplexing to improve performance and transmission rate. In this paper we investigate trade offs between different techniques in broadband OFDM-based MIMO systems for achieving full diversity or maximum spatial multiplexing gain. The basic model of OFDM-based spatial multiplexer is very suitable for high data rate transmission, and if combined with other techniques such as channel coding or space time coding can provide desired diversity and spatial multiplexing gain.
