Non-Orthogonal Multiple Access for Large-Scale 5G Networks: Interference Aware Design
IEEE Access, 2017 Non-orthogonal multiple access (NOMA) is promoted as a key component of 5G cellular networks. As the name implies, NOMA operation introduces intracell interference (i.e., interference arising within the cell) to the cellular operation.

Low-complexity hybrid interference cancellation for sparse code multiple access
EURASIP Journal on Wireless Communications and Networking, 2022 Sparse Code Multiple Access (SCMA) is one of Non Orthogonal Multiple Access (NOMA) candidates for 5G, the fifth generation mobile network. Multiple overlapped blocks of SCMA code are transmitted per frequency layer which compels the receiver to cancel ...

EURASIP Journal on Wireless Communications and Networking, 2018 Space-division multiple access (SDMA) utilizes linear precoding to separate users in the spatial domain and relies on fully treating any residual multi-user interference as noise. Non-orthogonal multiple access (NOMA) uses linearly precoded superposition
