In this paper, we focus on non-orthogonal multiple access (NOMA) network with power-domain user multiplexing at the transmitter side and successive interference cancellation (SIC) on the receiver side. The main problem presented in NOMA network is the design of the precoder. It has to be applied to users with weak channel conditions to effectively mitigate interference between cells. We propose a...
Among the key technologies that have been developed for efficient transmission for 5G, are spatial modulation (SM) and non-orthogonal multiple access (NOMA). In SM, multiple transmission antenna is modulated as information in order to increase capacity. On the other hand, NOMA allows to share the same frequency resources at the same time. Obviously, combination of these two techniques offers a new...
