Then, the relationships between them and the number of antennas were analyzed, and the optimal algorithm for maximizing the secondary throughput was also given. Simulation results demonstrated that lower miss-detection probability can be achieved in C-MA-CSS compared to the non-censoring CSS. Besides, the secondary throughput monotonically increased rapidly first and slowly after. Meanwhile, optimal secondary throughput can be achieved with smaller number of antennas by the proposed algorithm while maintaining the target detection probability. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2017.04.005
