Dynamic Rate Allocation in Fading Multiple-access Channels
We consider the problem of rate allocation in a fading Gaussian multiple-access channel (MAC) with fixed transmission powers. Our goal is to maximize a general concave utility func...

Closed-Form Capacity Expression for Transmit Antenna Selection Systems with Correlated Fading Channels
—In this paper, the exact closed-form capacity expression for a hybrid selection/MIMO (H-S/MIMO) system in the spatial correlated Rayleigh fading channels is investigated. There ...
