Abstract

This paper considers the multiuser multiple-input multiple-output (MIMO) Rayleigh fading broadcast channel. We consider the case where the multiple transmit antennas are used to deliver independent data streams to multiple users via a multi-user technique known as vector perturbation. We derive expressions for the capacity in terms of the average energy of the precoded vector, and use this to derive a closed-form high-SNR upper bound, which we show to be tight via simulation. We then turn to the practical issue of user selection. We propose a low-complexity user selection algorithm that attempts to maximize the high-SNR sum rate upper bound. Simulations show that the algorithm outperforms other user selection algorithms of similar complexity.

Period	14/06/09 → 18/06/09
Other	Since 1965 the IEEE International Conference on Communications is one of the flagship conferences of the IEEE Communications Society. It brings together the world's leading scientists from academia and industry. Recent advances in the field of communications will be presented, thereby facilitating scientific idea exchange, the identification of future trends in communications, and the illumination of business opportunities. The conference has been hosted at the International Congress Center, located at the scenic banks of the Elbe river and embedded in the cultural center of Dresden.
