Joint User Grouping and Decoding Order in Uplink/Downlink MISO/SIMO-NOMA
IEEE Access, 2020 In this paper, we design and investigate a novel uplink/downlink (UL/DL) non-orthogonal multiple access (NOMA) network using a common relay. Instead of successive interference cancellation (SIC) for UL/DL NOMA systems with fixed decoding order based on ...

Dynamic Beam Hopping Algorithm for LEO Satellite Systems Based on User Grouping
天地一体化信息网络, 2023 In a satellite communication system deployed with massive MIMO, when the number of users far exceeds the number of beams of the satellite, it is still difficult to satisfy the delay requirements of the satellite communication system even if the number of
