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…
Asymptotic Independence in the Spectrum of the Gaussian Unitary Ensemble
P. Bianchi, M. Debbah, J. Najim
Consider a matrix from the Gaussian Unitary Ensemble (GUE). Given a finite collection of bounded disjoint real Borel sets , properly rescale…
A maximum entropy approach to OFDM channel estimation
Romain Couillet, Merouane Debbah
In this work, a new Bayesian framework for OFDM channel estimation is proposed. Using Jaynes' maximum entropy principle to derive prior information, we successively tackle the situ…
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…
