—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)
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)
