Smart gateways for terabit/s satellite

Abstract

SUMMARY To reach the terabit per second of throughput, telecommunication satellites cannot make use of frequency below Ka band only. Therefore, the use of broad portion of the spectrum available at Q/V (40/50 GHz) band is foreseen for the feeder link. This study presents the evaluation of performances of different macro-diversity schemes that may allow mitigating the deep fades experienced at Q/V bands by introducing cooperation and a limited redundancy between the different gateways of the system. Two different solutions are firstly described. The performances resulting from the use of those assumptions are derived in a second stage. Copyright © 2014 John Wiley & Sons, Ltd. This paper describes macro-diversity solutions to mitigate the effect of the propagation impairments for the feeder links of high throughput satellite. Preliminary performance assessments are performed on two possible designs. Copyright © 2014 John Wiley & Sons, Ltd.
