Cooperative transmission schemes can offer benefits in terms of diversity and multiplexing gain compared with conventional direct transmission by forming a virtual antenna array. I...
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,...
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...
— We consider a multiple access channel (MAC) with multiple antennas, where each user has different diversity and multiplexing gain requirement. For this configuration, we chara...
We establish the optimal diversity-multiplexing (DM) tradeoff of coherent selective-fading multiple-access multiple-input multiple-output (MIMO) channels and provide corresponding ...
