Effect of transmit antenna correlation on multiuser diversity

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
In this paper, we investigate throughput performance of downlink multi-antenna transmission schemes exploiting multiuser diversity. The asymptotic analysis is performed based on the extreme value theory. From this analysis, it is demonstrated that the multiuser spatial multiplexing known as the asymptotically optimal transmission scheme is no longer ...

Antenna transmit diversity for wireless OFDM systems

Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003
We investigate several transmit-diversity techniques for wireless OFDM systems employing multiple antennas. We concentrate our investigation on methods that can be applied with few modifications to existing standards. Existing methods such as delay diversity, clustering and antenna interleaving are investigated and compared.

On the matched filter bound of transmit diversity techniques

ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002
Diversity transmission at the base station is an effective technique to combat the adverse effects of fading. This is suggested as an alternative to diversity at the terminal, thereby reducing the implementation complexity. We evaluate the matched filter bound (MFB) for two transmit diversity schemes with two transmit antennas: delay diversity and ...
