On the Analysis and Design of Practical Quantization for Opportunistic Beamforming
Abstract—We propose a closed–loop scheme that combines opportunistic beamforming (OBF) and closed–loop (CL) transmit–diversity (TD) techniques. This quantized OBF scheme is...

On the Stability and Delay of Channel-Aware Slotted ALOHA with Imperfect CSI
—In this work, we study the effect of imperfect channel-state information (CSI) on the stability and delay of a two-user channel-aware slotted ALOHA system. We assume that the ch...
