| Abstract: | Two robust secure beamforming(BF)schemes are proposed for multiple eavesdroppers in downlink of a multi-beam satellite communication system,where only the approximate locations of multiple eavesdroppers are known.On one hand,under the secrecy rate maximization criterion subject to the total satellite transmit power constraint,and a robust BF scheme based on the generalized Rayleigh quotient is proposed to obtain the analytical expression of BF weight vector.On the other hand,in order to obtain the maximal secrecy energy efficiency under the constraints of the secrecy rate and the total satellite transmit power,a nested iterative algorithm based on the combination of fractional programming,penalty function and difference of convex programming theory is proposed to implement the robust BF design.Simulation results show that the proposed two robust BF schemes can obtain better secrecy performance than the classical non-robust BF schemes. |
