Exact outage probability of a hybrid satellite terrestrial cooperative system with best relay selection

Abstract

In this paper, we derive the exact outage probability of a hybrid satellite-terrestrial cooperative system (HSTCS). A selective decode-and-forward scheme is implemented between a source node (the satellite) and a destination node (a terrestrial station), and a selection of the best relay terminal is performed. In this proposed system, a two time-slot scenario is considered. During the first time slot, the satellite is broadcasting the information to the terrestrial relays and the destination. In the second time slot, only the best relay is transmitting toward the destination node. Then, both signals are combined using the maximum ratio combining (MRC) technique. The analytical expression of the outage probability is evaluated and is then verified with the simulation. The results show that our analytical expression matched well to the simulation results.

Beamforming schemes for hybrid satellite-terrestrial cooperative networks

“…However, in an actual environment, the coverage area of satellite network is often limited by the masking effect, which makes the line-of-sight (LOS) link between satellite and terrestrial terminal unavailable [1]. To overcome this problem, the concept of hybrid satellite-terrestrial cooperative network (HSTCN) has been proposed and studied [2][3][4].…”

Outage Performance of Cognitive Hybrid Satellite–Terrestrial Networks With Interference Constraint

“…Under this situation, many researches have investigated the key performance merits of satellite communications, such as outage probability (OP), average symbol error rate (ASER) and ergodic capacity [4]- [8]. However, the increasingly growing number of applications and services of satellite communication is rapidly exhausting the limited spectral resources, and therefore exploring new techniques to enhance spectrum efficiency in satellite communication has become an important research issue.…”

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

“…Among them, by assuming that maximal ratio combining (MRC) is adopted at destination, the authors of [3] have evaluated the average symbol error rate (ASER) of HSTCN with variable gain amplify-and-forward (AF) relaying, and an extension work to the fixed gain AF relaying can be found in [4], where the asymptotic results at high signal-to-noise-ratio (SNR) have also been provided. In [5], the authors have derived the exact outage probability (OP) expressions of a HSTCN with best relay selection scheme operating in decode-and-forward (DF) protocol. In [6], the authors have investigated the performance of AF-based hybrid satellite-terrestrial free space optical (FSO) cooperative systems, where both the approximate ASER expression and analytical diversity order are obtained.…”

“…PROBLEM FORMULATION Consider a HSTCN, where a satellite (S) communications with a terrestrial destination (D) via a terrestrial relay (R). In this network, each node is equipped with single antenna, and the S-D and S-R links undergo the shadowed-Rician fading while the R-D link follows the Rayleigh fading [5]. The overall communication occurs in two time slots.…”
