Cognitive radio networks (CRNs) and non-orthogonal multiple access (NOMA) have emerged as complementary solutions to address spectrum scarcity and the ever-growing demand for wireless connectivity.
Access methods are multiplexing techniques that provide communications services to multiple users in a single-bandwidth wired or wireless medium. Communications channels, whether they’re wireless ...
Non-Orthogonal Multiple Access (NOMA) represents a paradigm shift in the allocation of spectral resources by allowing multiple users to share the same time–frequency slot, differentiated in the power ...
