Abstract |
This paper presents an eigen-value based cooperative spectrum sensing (SS) technique in the presence of noise correlation for Cognitive Radio (CR). In this work, a new Standard Condition Number (SCN) based decision statistics is defined using asymptotic random matrix theory (RMT) for the decision making process. First, the effect of noise correlation under both noise only and signal plus noise hypothesis is defined. Then the new bounds for the correlated noise scenario are defined and a the new SCN based threshold is derived for SS in CR. Simulation results show that sensing with the proposed threshold gives better performance in the presence of noise correlation.
