“…We have assumed that the channel between the source and the relay nodes has LOS communication ( = 26) and the channel between the relay and destination node experience multipath fading. In this case we can allocate equal power at both the source and relay nodes [6]. The targeted threshold rate is chosen as 1 bit/sec/Hz to evaluate the outage probability of the system.…”

“…In [4], transmit diversity technique using space time coding (STC) is proposed and diversity gain is achieved with the use of multiple terrestrial relay nodes with encoding capabilities, while additional coding gain can be achieved at the destination node by combining different parity symbols as shown in [5]. Moreover, a comparison of AF and DF techniques in a cooperative satellite communication network is discussed in [6]. In [8], the architecture of a satellite based mobile multimedia broadcasting is presented, while cooperative relaying for DVB-SH is discussed in [9] - [10].…”

This paper investigates a hybrid satellite-terrestrial cooperative relaying communications network (HSTCN) under independent and non-identical shadowed Rician and Nakagami-m fading channels. It evaluates the performance of such a network using amplify-and-forward (AF) cooperative relaying protocol. The maximal ratio combining (MRC) technique is used at the destination to combine the signals received from the source and cooperating relay nodes. An analytical approach is derived to evaluate the performance of the system in terms of outage probability and symbol error rate (SER). The closed form expressions for the probability density function (PDF), cumulative distribution function (CDF) and moment generating function (MGF) of the end-to-end signal to noise ratio (SNR) are also derived. The derived analytical expressions are applied to the general operating conditions with the help of satellite channel data available from the literature. The analytical results are compared with Monte Carlo simulations. The results show the improvement in the performance of the HSTCN under challenging fading conditions with the help of fixed multiple terrestrial relay nodes

“…Cooperation among the devices is also exploited in 4G satellite networks, thus raising several issues, such as synchronization, bandwidth allocation, and selection of forwarding and relaying devices [45]. In [46], two cooperation schemes, namely, Decode-Forward and Amplify-Forward, have been analyzed with the aim to determine, which solution can offer better data forwarding capabilities from the satellite to the mobile terminal, even when the latter moves into the areas that are unreachable from the satellite.…”

Fifth-generation (5G) telecommunication systems are expected to meet the world market demands of accessing and delivering services anywhere and anytime. The Non-Terrestrial Network (NTN) systems are able to satisfy the requests of anywhere and anytime connections by offering wide-area coverage and ensuring service availability, continuity, and scalability. In this work, we review the 3GPP NTN features and their potential for satisfying the user expectations in 5G & beyond networks. The state of the art, current 3GPP research activities, and open issues are summarized to highlight the importance of NTN over the wireless communication landscape. Future research directions are also identified to assess the role of NTN in 5G and beyond systems.

The concept of relay transmission is applied to Land Mobile Satellite (LMS) communication where a terrestrial relay node forwards information from the satellite to the mobile unit. Two hop Amplify and Forward (AF) and Decode and Forward (DF) cases are considered where source, relay and destination, all are equipped with multiple antennas, using Maximal Ratio Transmission (MRT)-Selection Combining (SC) diversity technique for the first hop and Maximal Ratio Combining (MRC) for the second hop. We present analysis of both AF and DF in terms of outage probability and Symbol Error Rate (SER) for which closed form expressions are derived and show that DF always outperforms AF. Results are illustrated through several examples in order to assess the impact of multiple antennas at the nodes and shadowing severity parameter m on the performance.
