Symbol Error Analysis of Hybrid Satellite–Terrestrial Cooperative Networks With Cochannel Interference

Abstract

This letter investigates the effect of cochannel interference (CCI) on a hybrid satellite-terrestrial cooperative relay network (HSTCN), where both the satellite-destination and satellite-relay links undergo the shadowed Rician fading, whereas the relay-destination link follows the Rayleigh fading. By assuming that decode-and-forward (DF) protocol is adopted at the terrestrial relay, and the destination is corrupted by multiple CCI, we first derive the analytical expression for the moment generating function (MGF) of the output signal-to-interference-plus-noise ratio (SINR). Then, based on the Meijer-G functions, we present an approximated yet accurate method to evaluate the average symbol error rate (ASER) of the cooperative network. Moreover, the asymptotic ASER at high signal-to-noise ratio (SNR) with respect to diversity order and array gain are also given to gain further insights. Finally, numerical results are provided to demonstrate the validity of the performance analysis as well as the impact of CCI on the HSTCN.Index Terms-Decode-and-forward relaying, hybrid satelliteterrestrial cooperative network, cochannel interference.

Robust Chance-Constrained Secure Transmission for Cognitive Satellite–Terrestrial Networks

“…For instance, the hybrid satellite-terrestrial cooperative networks were investigated in [13]- [17] based on Digital Video Broadcast-Satellite Handheld (DVB-SH) standard. In this situation, many researchers have analyzed the performance of hybrid satellite-terrestrial networks in single antenna [16], [18] and multi-antenna [17] scenarios, respectively. It is foreseeable that the number of connected devices will exceed 20 billion until 2020, which requires extra spectrum resources.…”

Performance Analysis of Multi-Antenna Hybrid Satellite-Terrestrial Relay Networks in the Presence of Interference

“…Due to the reuse of spectrum resources in practice, the major challenges facing the hybrid satellite-terrestrial networks is the problem of interference from inter-component and/or intra-component [24]. While [25] has firstly investigated the ASER performance of the HSTRNs with CCIs at the destination for the single antenna scenario, the ergodic capacity, OP, and ASER have not been studied in the case that the satellite and terrestrial user have multi-antenna and CCIs corrupting both the relay and destination nodes. It is crucial to study this problem.…”

“…Since R and D are two terrestrial nodes, the relay-destination link is often assumed to undergo Rayleigh or Nakagami-m fading distribution distribution [8], [16], [25]. Without loss of generality, we consider the terrestrial link h 2 follows the Rayleigh fading and, the PDF and…”

Internet of Things-Enabled Overlay Satellite-Terrestrial Networks in the Presence of Interference

“…Note that, in STNs, the co-channel interference originating from both extra-terrestrial (i.e., satellite interferers) and terrestrial (i.e., ground interferers) sources is inevitable. Consequently, the works in [6], [13], [14] have analyzed the performance of STNs in the presence of terrestrial interferers only. However, the literature analyzing the performance of cognitive STNs with interference is sparse.…”
