While full-duplex techniques are gaining interest in terrestrial communications, thanks to the trend of short-distance and low-power transmissions, their application to satellite communications has drawn little attention. Motivated by this, the paper explores the use of the full-duplex relaying operation on-board the satellite in a DVB-S2 compliant network. Self-interference, whose management is the key component of a full-duplex communication, is the focus of study in this paper. Modelling the effects of self-interference and power amplifier nonlinearities on the quality of the received signal in undertaken. Subsequently, closed-form expressions for the various interference components are derived. The numerical evaluations of derived expressions rely on realistic link budgets and indicate substantial gains in spectral efficiency when self-interference can be well calibrated and measured. This confirms that the satellite full-duplex communications could be a promising solution for the efficient use of satellite spectrum, at least from a technical point of view.  \nI. INTRODUCTION  \nThanks to their wide coverage, satellites serve as an effective forato provide broadcast and interactive broadband services, especially to geographical areas under-served by terrestrial infrastructure. In atypical architecture, satellite acts as a relay for conveying information from the on-ground transmitter to an on-ground receiver. Towards satisfying an increased demand for high throughput from satellite networks, several techniques and technologies have been considered towards enhancing the spectral efficiency of satellite communications either by acquiring additional spectrum or better utilization of existing ones. A typical example for the former is the considered migration to Q/V bands and optical communications. Use of additional spectrum is influenced by existing regulations and technological maturity of the component sub-systems. Better utilization of the existing spectrum is currently been pursued through enhancements to DVB-S2 standard [1], [2], multibeam architectures with associated flexibility [3], full frequency reuse [4] and cognitive techniques [5] amongst others.  \nFull-duplex communications, where a node receives and transmits simultaneously in the same frequency band, has received much attention recently for its potential to double the transmission rate or save half the bandwidth [6], [7], [8] . However, in reality, the ideal gains are reduced by the self-interference (SI) phenomenon arising due to leakage of signal power from the transmitted waveform onto the waveform being received [9] . Hence a key aspect towards incorporation of full-duplex paradigm involves an analysis of the tolerable self-interference levels followed by an implementation of compensation techniques to achieve the said interference level. The SI cancellation can be broadly categorized as passive cancellation and active cancellation [6] . Passive suppression is to isolate the transmit and receive antennas [10] . Active suppression is to exploit anode’s knowledge of its own transmit signal to cancel the SI, which typically includes analog cancellation and digital cancellation [11] . In the recent work [12] and [13], the promising results show that the SI can be suppressed to the nois","cbCaii6FtsyKlRlT","https://ap.wps.com/l/cbCaii6FtsyKlRlT","pdf",266302,"English","# Introduction\n## Background and motivation\n## Self-interference and cancellation approaches\n## Full-duplex relaying in satellite systems","[{\"question\":\"What is the main focus of the paper?\",\"answer\":\"The paper studies the feasibility of using full-duplex relaying onboard satellites in a DVB-S2 compliant network, with emphasis on modeling and managing self-interference.\"},{\"question\":\"Why is self-interference critical for full-duplex communication?\",\"answer\":\"Full-duplex requires simultaneous transmit and receive on the same band, but leakage from the transmitted signal onto the received waveform creates self-interference that reduces ideal gains unless mitigated.\"},{\"question\":\"How do the results evaluate whether full-duplex relaying is worthwhile?\",\"answer\":\"The paper derives closed-form expressions for interference components and numerically evaluates them using realistic link budgets, showing spectral-efficiency gains when self-interference can be well calibrated and measured.\"}]","Feasibility Study of Full-duplex Relaying in Satellite Networks | PDF",13]
