Demonstration of 5G non-terrestrial network regenerative L1 processing

The regenerative architecture for 5G Non-Terrestrial Networks (NTNs) offers several advantages over the transparent architecture, including reduced latency, improved quality of service, lower feeder link bandwidth, support for inter-satellite links and the provision of edge compute services. However, it has the challenge of requiring computationally intensive 5G base stations to be placed into the Low-Earth Orbit (LEO) satellites, rather than into ground stations as is done in the transparent architecture. Based on AccelerComm's portfolio of flexible O-RAN L1 solutions, this paper describes a demonstration of a low-power radiation-tolerant 5G base station L1 implementation which addresses this challenge, making it suitable for LEO satellite deployment.
