OFDM-Based Massive Connectivity for LEO Satellite Internet of Things
IEEE Transactions on Wireless Communications, 2023 Low earth orbit (LEO) satellite has been considered as a potential supplement for the terrestrial Internet of Things (IoT). In this paper, we consider grant-free non-orthogonal random access (GF-NORA) in orthogonal frequency division multiplexing (OFDM) system to increase access capacity and reduce access latency for LEO satellite-IoT.
