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…
A Bayesian Framework for Collaborative Multi-Source Signal Detection
Romain Couillet, Merouane Debbah
This paper introduces a Bayesian framework to detect multiple signals embedded in noisy observations from a sensor array. For various states of knowledge on the communication chann…
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…
