—We demonstrate that receive antenna selection (RAS) provides significant increase in the achievable sum rates for multiuser MIMO wireless downlinks that employ block diagonalization (BD) to achieve orthogonal space division multiplexing (OSDM), where each user terminal has one or more antennas. Although dropping one or more receive antennas at a user(More)
—The need for high downlink throughput has led to the consideration of multiple-input multiple-output (MIMO) systems with multi-antenna user terminals. Spatial multiplexing via orthogonal space division multiplexing (OSDM) may be achieved using block diagonalization (BD) techniques. User subset selection is required when the potential user pool exceeds the(More)
I. INTRODUCTION The demand for high transmission rates to mobile users over a limited frequency spectrum has led to the consideration of multiple-input multiple-output (MIMO) techniques in wireless systems. The demand is particularly challenging in wireless network downlinks, which constitute point-to-multipoint links or broadcast channels. When full(More)
—We demonstrate that judicious receive antenna selection (RAS) can be used to create room for scheduling more users while minimizing the rate loss of existing users for multiuser MIMO wireless downlinks that employ block diagonalization (BD) to achieve orthogonal space division multiplexing (OSDM), when each user terminal has multiple antennas. When coupled(More)
