Non-Terrestrial Networks (NTNs): Where Cellular and SatCom Converge
Ubiquitous internet connectivity using satellites is no longer a dream, as demonstrated by the 3GPP investment in 5G non-terrestrial networks (NTNs). This microapp will describe the challenges of NTN links, which significantly differ from those of terrestrial links, as they must deal with larger propagation delays and high Doppler. It will also describe the modeling and simulation required to design these links. We will discuss MATLAB simulations of orbit propagation, power amplifier (PA) models, Doppler compensation, 5G OFDM processing, and link throughput as a function of SNR.
