| Abstract(in English) | In the physical layer security (PLS), since the beam forming with multiple antennas enhances the received signal power at the legitimate user but suppresses it at the other user, the other user hardly demodulate the information without the bit error. However, if the channel transfer function between the legitimate user and the other one is highly correlated, it is possible for the other user to demodulate the information signal. This paper proposes the novel secure communication system with utilizing the artificial noise and the relay station. In the proposed system, the other user hardly demodulates the information signal due to the artificial noise. When the legitimate user emits the artificial noise, it can remove the artificial noise from the combined signal between the information signal and the artificial noise. As a result, the only legitimate user can demodulate the information signal. This paper evaluates the secure capacity for the various location of eavesdropper and clarifies the validity of proposed system. |
