Scheduling and Pre-Conditioning in Multi-User MIMO TDD Systems
Abstract—The downlink transmission in multi-user multipleinput multiple-output (MIMO) systems has been extensively studied from both communication-theoretic and information-theor...

Contrabass: concurrent transmissions without coordination
A PHY and MAC protocol for MIMO concurrent transmissions, called Contrabass, is presented. Concurrent transmissions, also referred to as multi-user MIMO, are simultaneous transmis...

Joint channel estimation and resource allocation for MIMO systems-part I: single-user analysis
Multiple antenna systems are known to provide very large data rates, when the perfect channel state information (CSI) is available at the receiver. However, this requires the recei...

Near Optimum Power Control and Precoding under Fairness Constraints in Network MIMO Systems
Abstract--We consider the problem of setting the uplink signalto-noise-and-interference (SINR) target and allocating transmit powers for mobile stations in multicell spatial multip...

Asymptotic Capacity and Optimal Precoding in MIMO Multi-Hop Relay Networks
A multi-hop relaying system is analyzed where data sent by a multi-antenna source is relayed by successive multi-antenna relays until it reaches a multi-antenna destination. Assum...
