Performance improvement techniques for the DVB‐RCS2 return link air interface

International Journal of Satellite Communications and Networking, 2015
SummaryThis paper presents performance improvement techniques for the second‐generation digital video broadcast return channel via satellite air interface, which can be used for supporting future demands for Tbit/s traffic requirements. In particular, we have investigated minimum‐shift keying (MSK) type of continuous phase modulation (CPM) waveforms by

Uncertainty Characterization Framework for Machine Learning Based ACM in Q‐Band Satellite Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Adaptive coding and modulation (ACM) is a widely utilized technique in satellite communication networks to mitigate the adverse effects of rain fades, particularly in extremely high frequency (EHF) bands. As a core component of fade mitigation techniques (FMTs), ACM improves signal resilience.

Simulation of the Effect of Interference and EIRP on the Qos of DVB-S2 and DVB-RCS2 Networks

JETISH: Journal of Education Technology Information Social Sciences and Health, 2023
The purpose of this study was to obtain the QoS value of the data sent from the user terminal to the gateway based on variations in antenna gain and to determine the effect of the level of interference caused by noise on the user's device on the quality of data reception. This research uses the NS3 software experimental method.
