Limited Feedback for Temporally Correlated MIMO Channels with Other Cell Interference
Salam Akoum, Robert W. Heath
Limited feedback improves link reliability with a small amount of feedback from the receiver back to the transmitter. In cellular systems, the performance of limited feedback will…
Adaptive Limited Feedback for Sum-Rate Maximizing Beamforming in Cooperative Multicell Systems
Ramya Bhagavatula, Robert W. Heath
Base station cooperation improves the sum-rates that can be achieved in cellular systems. Conventional cooperation techniques require sharing large amounts of information over fini…
The Feasibility of Interference Alignment over Measured MIMO-OFDM Channels
Omar El Ayach, Steven W. Peters, Robert W. Heath
Interference alignment (IA) has been shown to achieve the maximum achievable degrees of freedom in the interference channel. This results in sum rate scaling linearly with the numb…
End-to-End Joint Antenna Selection Strategy and Distributed Compress and Forward Strategy for Relay Channels
Rahul Vaze, Robert W. Heath
Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time…
Multi-mode Transmission for the MIMO Broadcast Channel with Imperfect Channel State Information
Jun Zhang, Marios Kountouris, Jeffrey G. Andrews +1
This paper proposes an adaptive multi-mode transmission strategy to improve the spectral efficiency achieved in the multiple-input multiple-output (MIMO) broadcast channel with del…
