Exploiting Sparse User Activity in Multiuser Detection
—The number of active users in code-division multiple access (CDMA) systems is often much lower than the spreading gain. The present paper exploits fruitfully this a priori infor...

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...

Multiuser linear precoding for cooperating base stations with asynchronous interference
— This paper addresses multiuser linear precoding using multiple cooperating base stations (BSs). All BSs, and potentially the users, are equipped with multiple antennas. Prior w...

A multi-threshold scheme for feedback load reduction in multiuser MIMO broadcast channel
In a multiuser system, independent time-varying channels among different users can be exploited to provide multiuser diversity (MUD) gain and increase the system throughput. For th...
