Asynchronous uplink non-orthogonal multiple access (NOMA) with cyclic prefix
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018 Non-orthogonal multiple access (NOMA) has been recognized as a promising technique for future radio access. In this paper, different from [3], it is proposed that the cyclic prefix (CP) is used in the asynchronous uplink NOMA transmission for mitigating asynchronous effects. Through analyzing the inter-user interference (IUI) and residual interference,

Non-Orthogonal Multiple Access (NOMA) to Enhance Capacity in 5G
International Journal of Contents, 2015 Non-orthogonal multiple access (NOMA) where all users share the entire time and frequency resource has paid attention as one of the key technologies to enhance the spectral efficiency and the total throughput. Nevertheless, as the number of users and SIC error increase, the inter-user interference and the residual interference due to the SIC error also
