Trading Rate for Balanced Queue Lengths for Network Delay Minimization
—We consider a communication channel with two transmitters and one receiver, with an underlying rate region which is approximated as a general pentagon. Different from the Gaussi...

On the Sum-Rate of Opportunistic Beamforming Schemes with Multiple Antennas at the Receiver
Abstract— The capacity region of Gaussian Multi-InputMultiple-Output (MIMO) broadcast channels has been shown to be achieved by dirty paper coding (DPC). However, due to the high...
