Verifying a concept of adaptive communication with LEO satellites using SDR-based simulations

Abstract

The paper is related to an adaptive satellite communication system for data transmission from small, low cost, low Earth orbit satellites. Tests run in a set-up consisting of a number of software-defined radio (SDR) modules operating as a satellite, a ground station, and a satellite channel simulator, have shown that by changing modulation scheme and code rate one can obtain increase of amount of data which can be downloaded from a satellite during a single pass over a ground station approximately by a factor of 2. To determine data rates obtainable in an SDR system using a common personal computer as a digital signal processing device, execution times of particular processing steps involved in the reception process were measured.

“…The results of simulation and experiments obtained for the wired and wireless synchronization between the nodes are presented and discussed in the paper. The last paper [7] is one of many papers presented during MRW 2018 that are related to space technology. The paper deals with a concept of adaptive communication with low Earth orbit (LEO) satellites.…”
