Power Control for User Cooperation
For a fading Gaussian multiple access channel with user cooperation, we obtain the optimal power allocation policies that maximize the rates achievable by block Markov superpositi...

Diversity-Multiplexing Tradeoff in Selective-Fading Multiple-Access MIMO Channels
We establish the optimal diversity-multiplexing (DM) tradeoff of coherent selective-fading multiple-access multiple-input multiple-output (MIMO) channels and provide corresponding ...

The General Gaussian Multiple Access and Two-Way Wire-Tap Channels: Achievable Rates and Cooperative Jamming
—The general Gaussian multiple-access wiretap channel (GGMAC-WT) and the Gaussian two-way wiretap channel (GTW-WT) are considered. In the GGMAC-WT, multiple users communicate wit...

Effect of Channel Estimation Errors on Diversity-Multiplexing Tradeoff in Multiple Access Channels
Abstract— In this paper, multiple access channels are considered in which user data rates increase with the signal-to-noise ratio (SNR). To account for channel estimation errors,...

MIMO Multiple Access Channels with Noisy Channel Estimation and Partial CSI Feedback
Abstract—We consider correlated MIMO multiple access channels with block fading, where each block is divided into training and data transmission phases. We find the channel esti...
