Exponential Diversity Achieving Spatio-Temporal Power Allocation Scheme for Fading Channels
In this paper, we analyze optimal (in space and time) adaptive power transmission policies for fading channels when the channel-state information (CSI) at the transmitter (CSIT) an...

Diversity Multiplexing Tradeoff in Multiple Antenna Multiple Access Channels with Partial CSIT
Abstract— We derive a lower bound on the diversitymultiplexing tradeoff for multiple antenna multiple access channels using temporal power control (PC). We quantify the substanti...

Regularized Channel Inversion for Multiple-Antenna users in Multiuser MIMO Downlink
— Channel inversion is one of the simplest techniques for multiuser downlink systems with single-antenna users. In this paper, we extend the regularized channel inversion techniq...
