Secrecy outage analysis of satellite communication networks with hardware impairments and channel estimation errors

Abstract

This Letter investigates the impacts of hardware impairments (HIs) and channel estimation errors (CEEs) on the secrecy performance of satellite communication networks with one legitimate user and one eavesdropper. Particularly, the authors derive the closed‐form expression for the secrecy outage probability (SOP) of the considered secrecy satellite communication networks. Besides, in order to research the impact of the HIs and CEEs at high signal‐to‐noise ratios, they obtain the asymptotic expression for the SOP, which gives efficient and fast method to evaluate the effect of the considered system parameters on the secrecy system performance. At last, Monte Carlo computer results are given to verify the effects of HIs and CEEs on the secrecy system performance.

Secrecy Analysis of NOMA-Based Integrated Satellite-Multiple UAV Networks under Nonideal Hardware and Colluding Scheme

“…Until now, the impact of nonideal hardware on the NOMA-based SatCom was only investigated in several former papers, such as [31][32][33][34]. In [31], the authors analyzed the SOP for the considered SatCom with nonideal hardware and channel estimation errors (CEEs). In [32], the impact of nonideal hardware was investigated for the ISTRNs.…”
