The Poisson Multiple-Access Channel
—The Poisson multiple-access channel (MAC) models many-to-one optical communication through an optical fiber or in free space. For this model we compute the capacity region for ...

Resource Allocation in Multiple Access Channels
We consider the problem of rate allocation in a Gaussian multiple-access channel, with the goal of maximizing a utility function over transmission rates. In contrast to the literat...

On resource allocation in fading multiple-access channels-an efficient approximate projection approach
We consider the problem of rate and power allocation in a multiple-access channel. Our objective is to obtain rate and power allocation policies that maximize a general concave ut...

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...
