“…Therefore, it is of great necessity to conduct further research concerning the application of multiantenna systems in a personal SATCOM scenario at the SAT, user terminal, and earth station level. For example, the antenna size, the number of antennas required, interference mitigation, the use of codes, resource allocation, optimal beamforming architectural design, to mention but a few (Yingda et al, 2006;Alegre-Godoy and Vazquez-Castro, 2013;Mysore et al, 2021).…”

The unrelenting technological advancement in the generation of wireless networks in recent years has awakened the motion concerning the inclusion of satellites in personal communications. Leveraging their ability to provide wide coverage, uniform services, wide bandwidth, and so forth, Satellite systems will be expected to co-exist with the current state-of-the-art infrastructure of terrestrial networks. Herein, we present a comparative study on the representative digital modulation techniques for use in personal satellite communications. We discuss the advantages and limitations of different modulation techniques, such as phase shift keying, continuous phase modulation, amplitude phase shift keying, and quadrature amplitude modulation. We also perform evaluations based on spectral efficiency, power efficiency, modulation error ratio, error vector magnitude, and peak-to-average power ratio in the presence of high power amplifier nonlinearities and Doppler effects. Comparisons in the form of tables, illustrations, and curves are also presented. In correspondence to the comparisons made basing on the aforementioned metrics, we conclude that continuous phase modulation is the best candidate modulation scheme for personal satellite communications since it outperforms other schemes by compromising the trade-off between power efficiency, bandwidth efficiency, and immunity to errors. We further present open issues that would reinforce personal satellite communications in terms of reliability, throughput and latency, other than power and spectral efficiency, if combined with appropriate modulation schemes.

“…Numerous efforts have subsequently been attempted; these efforts focused on elucidating if network coding can provide additional advantages compared to other cooperative networking schemes. For example, network coding over the binary field [3], [4] has shown to improve diversity gain and provide higher spectral efficiency in wireless networks, whereas network coding with a nonbinary field further increase those benefits [5]- [9]. In particular, numerous studies have investigated the extent to which network coding can improve the performance of media access control and routing protocols, in terms of energy efficiency [22], transmission delay [24], and throughput [23], [25], compared to traditional forwardand-relay only based designs [19]- [21].…”

In this paper, we consider a cooperative wireless network in which there are multiple sources and multiple relays. Owing to unreliable wireless channels, the quality of network links between nodes can vary. This results in the failure of intermediate nodes that generate linear combinations of incoming messages in network coding schemes. We propose an analytical framework to evaluate the recovery performance of source messages at the base station. To this end, we consider a random transmission matrix in which each element of the transmission matrix is processed a random variable, where its distribution is a function of the outage probability. We derive an upper bound for the reconstruction performance, i.e., decoding failure probability and nullity. The proposed framework provides an evaluation tool that enables us to investigate the impact of a large number of sources and relays, as well as the field size of the network codes on system performance.

“…Bao et al [6] propose a cooperation scheme termed adaptive network-on-graph with the codes-on-graph to construct efficient linear network codes accounting for the changing the lossy nature of wireless networks. In [7], the authors investigate the diversity gain offered at high signal-to-noise ratio by applying network coding to a wireless network, which contains distributed antenna system as well as one that supports user cooperation between users. The above analyzed the performances under the condition of symbol synchronization.…”

On the condition that there are no available cooperative peers, this paper proposes self-cooperative network coding. Self-cooperative network coding is that the sender makes use of time diversity technologies to offer cooperative information by itself. One advantage of self-cooperative network coding is that with the increase of the number of packets, successful transmission rate become high. Consequently, self-cooperative network coding provides a solution for reliable transmission of the large file in deep space under condition of low signal noise ratio of received signal and huge transmission delay.
