From Spectrum Pooling to Space Pooling: Opportunistic Interference Alignment in MIMO Cognitive Networks
S. M. Perlaza, N. Fawaz, S. Lasaulce +1
We describe a non-cooperative interference alignment (IA) technique which allows an opportunistic multiple input multiple output (MIMO) link (secondary) to harmlessly coexist with…
On the Benefits of Bandwidth Limiting in Decentralized Vector Multiple Access Channels
Samir M. Perlaza, Merouane Debbah, Samson Lasaulce +1
We study the network spectral efficiency of decentralized vector multiple access channels (MACs) when the number of accessible dimensions per transmitter is strategically limited.…
Interference Relay Channels - Part I: Transmission Rates
Brice Djeumou, Elena Veronica Belmega, Samson Lasaulce
We analyze the performance of a system composed of two interfering point-to-point links where the transmitters can exploit a common relay to improve their individual transmission r…
Interference Relay Channels - Part II: Power Allocation Games
Elena Veronica Belmega, Brice Djeumou, Samson Lasaulce
In the first part of this paper we have derived achievable transmission rates for the (single-band) interference relay channel (IRC) when the relay implements either the amplify-an…
Combining coded signals with arbitrary modulations in orthogonal relay channels
Brice Djeumou, Samson Lasaulce, Antoine Berthet
We consider a relay channel for which the following assumptions are made. (1) The source-destination and relay-destination channels are orthogonal (frequency division relay channel…
Power Allocation Games for MIMO Multiple Access Channels with Coordination
Elena Veronica Belmega, Samson Lasaulce, Merouane Debbah
A game theoretic approach is used to derive the optimal decentralized power allocation (PA) in fast fading multiple access channels where the transmitters and receiver are equipped…
