On the ergodic sum-rate performance of CDD in multi-user systems
— The main focus of space-time coding design and analysis for MIMO systems has been so far focused on singleuser systems. For single-user systems, transmit diversity schemes suff...

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,...

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 Rate Loss of Single-Letter Characterization: The "Dirty" Multiple Access Channel
For general memoryless systems, the typical information theoretic solution - when exists - has a "single-letter" form. This reflects the fact that optimum performance ca...

A Safe Multiple Access-Rates Transmission (SMART) Scheme for IEEE 802.11 Wireless Networks
Abstract— The IEEE 802.11 standard and enhanced amendments have defined fourteen transmission rates (1/2/5.5/6/9/11/12/ 18/22/24/33/36/48/54 Mb/s) for mobile stations to transmi...
