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 ...
