  • Spectrum sharing of Cognitive Radios (CRs) has broad application prospects to the new generation of wireless communication networks. In multi-cognitive-user circumstance, using tools from asymptotic random matrix theory, a new cooperative scheme for frequency band sensing is proposed. The property of asymptotic spectrum distribution of random matrices and the convergence of the maximum eigenvalue with low samples are well considered. Theoretical analysis and simulations results show that the new algorithm is obviously outperforming congener algorithms and classical energy detection techniques.
