| Abstract |
Physical layer security techniques have been studied in various models such as the MIMO system, multiple users, and relay scenarios combined with the artificial noise scheme that does not depend on the statistical characteristics of wireless channel. However, it is necessary to theoretically analyze the factors affecting the secrecy performance because the jamming strategies that are not elaborately established are rather detrimental to the performance. In this paper, we examined the change of security performances of the MIMO system regarding jamming power and node placements in the presence of eavesdroppers. |
