Cognitive OFDM network sensing: a free probability approach
Romain Couillet, Merouane Debbah
In this paper, a practical power detection scheme for OFDM terminals, based on recent free probability tools, is proposed. The objective is for the receiving terminal to determine…
Vandermonde Frequency Division Multiplexing for Cognitive Radio
L. S. Cardoso, M. Kobayashi, M. Debbah +1
We consider a cognitive radio scenario where a primary and a secondary user wish to communicate with their corresponding receivers simultaneously over frequency selective channels.…
Cooperative Spectrum Sensing Using Random Matrix Theory
L. S. Cardoso, M. Debbah, P. Bianchi +1
In this paper, using tools from asymptotic random matrix theory, a new cooperative scheme for frequency band sensing is introduced for both AWGN and fading channels. Unlike previou…
When Network Coding and Dirty Paper Coding meet in a Cooperative Ad Hoc Network
Nadia Fawaz, David Gesbert, Merouane Debbah
We develop and analyze new cooperative strategies for ad hoc networks that are more spectrally efficient than classical DF cooperative protocols. Using analog network coding, our s…
Constrained Cost-Coupled Stochastic Games with Independent State Processes
E. Altman, K. Avrachenkov, N. Bonneau +3
We consider a non-cooperative constrained stochastic games with N players with the following special structure. With each player there is an associated controlled Markov chain. The…
Maximum Entropy MIMO Wireless Channel Models
M. Guillaud, M. Debbah, A. L. Moustakas
In this contribution, models of wireless channels are derived from the maximum entropy principle, for several cases where only limited information about the propagation environment…
