摘要:Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are promising to overcome spectral scarcity problem encountered in applications implementations in wireless communication. Especially, massive connectivity in such network is strict requirement in network deployment. This study aims to improve spectral efficiency at two secondary destinations by investigating a CR-NOMA network under situation of the perfect successive interference cancellation (SIC). We also derive the exact outage probability for secondary users. Furthermore, an approximate computation method is applied to indicate more insights. It is confirmed that the performance achieved together with performance gap among two users can be obtained due to different power allocation factors assigned to users.
