In this paper, we propose a cooperative sensing method which allows to determine the unoccupied bands of the spectrum of wireless communication systems. Our approach is blind i.e., it does not require any cooperation between the transmitters and the sensors. We study the performance of the test in terms of probability of false alarm and miss probability. The theoretical analysis is based on results of Random Matrix Theory for spiked models.
