In this letter, the effect of hardware impairments on two-way satellite-terrestrial hybrid relay networks is analyzed. The terrestrial relay is considered as a two-way relay, which can transmit signals to both the satellite source and the mobile source simultaneously. Specifically, the closed-form expression, the asymptotic expression at high signal-to-noise rates and the throughput for the considered...
In this paper, we analyze the secure performance of satellite communication networks in Shadowed Rician Channel. It is very important to analyze the secure performance of the satellite-terrestrial networks. In this paper, both the Alice, Bob and Eve are equipped with single antenna respectively. Specifically, the exact closed-form expressions for the probability of non-zero secrecy capacity, the secrecy...
This paper investigates the secure transmit design of a cooperative hybrid satellite-terrestrial relay network (HSTRN). Assuming that amplify-and-forward (AF) protocol is adapted at terrestrial relays, and global channel state information (CSI) is known, we propose two schemes through jointly optimizing the relay beamforming vector and the covariance matrix of artificial noise (AN) to maximize the...
The hardware impairments of physical transceivers that create distortions degrade the performance of satellite relay communication. In this paper, we investigate the impact of hardware impairments on both the outage performance and the instantaneous capacity of dual-hop decode-and-forward (DF) satellite-relay network. Specifically, the exact closed-form expression for the outage probability of the...
