Abstract:
This paper investigates the secrecy performance of a multi-antenna land mobile satellite (LMS) communication system in the presence of an eavesdropper who wants to overhear the confidential message. Specifically, considering the active eavesdropping scenario, namely, the eavesdropper's CSI is available to the satellite, we derive the closed-form expression for the average secrecy capacity of the LMS system. Furthermore, we also provide the simple asymptotic average secrecy capacity formula at high signal-to-noise ratio (SNR). Based on the obtained asymptotic results, we obtain the high SNR slope as well as high SNR power offset of the LMS systems. Finally, numerical simulations are given to validate the theoretical analysis and indicate the effect of different system parameters on the secrecy performance of the considered systems.
