Abstract

Abstract

A physical layer security scheme is studied, which employs the advantage of artificial noise to improve the performance of legitimate user for multiple antenna systems using beamforming technology and artificial noise. Based on the transmitted symbols and channel coefficients, the sender determines whether or not the artificial noises are beneficial to the signal detection at the legitimate receiver. Then, beamforming vectors are designed accordingly. By taking advantage of useful noise, the signal to noise ratio at the legitimate receiver is improved effectively while that at the illegal receiver will remain the same. The bit error rate and the secrecy capacity are analyzed and simulated. The results demonstrate that the proposed scheme can improve the performance of the legal receiver and enhance secrecy capacity.
