摘要
Abstract
Multi-antenna spatial diversity and multi-users collaborative detection are key technologies for achieving the performances of spectrum detection in cognitive radio system.A spectrum sensing technique based on cyclostationary signatures for multi-antenna and multiple users is proposed.Each antenna receiver signal is combined according to maximal-ratio combining in the frequency domain,and the elementary spectrum verdict is made for the combined signals.The spectrum collaborative detection is performed according to the rule K/N for multiple users.The simulation results and analysis show that utilizing the cyclostationary signatures and the collaborative detection technique can improve the performances of spectrum sensing in cognitive radio system.关键词
