Multi-User MIMO Receivers With Partial State Information
Ahmad Gomaa, Louay M. A. Jalloul, Krishna S. Gomadam +2
We consider a multi-user multiple-input multiple-output (MU-MIMO) system that uses orthogonal frequency division multiplexing (OFDM). Several receivers are developed for data detec…
Approaching the Capacity of Wireless Networks through Distributed Interference Alignment
Krishna Gomadam, Viveck R. Cadambe, Syed A. Jafar
Recent results establish the optimality of interference alignment to approach the Shannon capacity of interference networks at high SNR. However, the extent to which interference c…
The Effect of Noise Correlation in AF Relay Networks
Krishna S. Gomadam, Syed A. Jafar
In wireless relay networks, noise at the relays can be correlated possibly due to common interference or noise propagation from preceding hops. In this work we consider a parallel…
Duality and Capacity Region of AF Relay MAC and BC
Syed A. Jafar, Krishna S. Gomadam
We consider multi-hop multiple access (MAC) and broadcast channels (BC) where communication takes place with the assistance of relays that amplify and forward (AF) their received s…
Optimal Relay Functionality for SNR Maximization in Memoryless Relay Networks
Krishna Srikanth Gomadam, Syed Ali Jafar
We explore the SNR-optimal relay functionality in a \emph{memoryless} relay network, i.e. a network where, during each channel use, the signal transmitted by a relay depends only o…
