| Outline of Final Research Achievements |
In this research, in order to dynamically utilize various types of spectrum resource for improving the spectrum efficiency based on cognitive radio, we focus on physical layer security techniques for the research of improving communication security. Here, we consider a novel multi-channel channel selection method, a beamforming algorithm suitable for spectrum leasing, improving security under a relay networks including unreliable relay node and so on. Finally, the effectiveness of the proposed methods are confirmed.
