Abstract
A multi-antenna spectrum sharing scheme is proposed based on primary activity. To maximize the cognitive system performance, two spectrum sharing optimization algorithms are designed, respectively for overlay and underlay. Simulation results show that the new spectrum sharing optimization algorithm improve the cognitive system performance with multi-antenna on the premise of protecting primary users.
