On the Performance Evaluations of Cooperative Retransmission Scheme for Cell-Edge Users of URLLC in Multi-Carrier Downlink NOMA Systems [PDF]
Sensors, 2021 Non-orthogonal multiple access (NOMA) has a key feature that the cell-center user (CCU) has prior information about the messages of the cell-edge user (CEU) in the same user-pair.

SCF Decoding Algorithm Based on Log Likelihood Ratio and Channel Polarization Reliability [PDF]
Jisuanji gongcheng, 2022 The traditional Successive Cancellation bit-Flipping(SCF) decoding algorithm only uses the absolute value of Log Like Ratio(LLR) to measure the reliability of information bit decoding results, which leads to a high Block Error Rate(BLER) and more ...
