Abstract
This paper proposes a novel power controlled sensing information gathering for cooperative sensing on shared spectrum with primary system while jointly using individual sensing results at each node. We apply simultaneous sensing information gathering by using an orthogonal frequency signal. This method can keep the interference power to the primary receiver low. Simulation results show that the power controlled cooperative sensing can obtain good sensing performance without harmful interference toward the primary system.
