Abstract:
Cooperative communication is one of the emerging technologies that promise significantly higher reliability
and spectral efficiency in wireless networks. It is a new form of diversity that allows users or nodes to share resources to create
collaboration via distributed transmission and processing of messages. As candidate multiple access for future radio access,
Non orthogonal multiple access (NOMA) over orthogonal multiple access (OMA) are adopted as downlink access scheme for
future 5th generation mobile communication. In this paper, we compare user throughput when using orthogonal multiple
access (OMA) and NOMA in macro femto network. We show through computer simulation the effect of imperfect interference
cancellation on user throughput. We assist the performance of user selection when using fixed power allocation. Finally, we
propose NOMA with COMP scenario whose performance improvement lead for user and cell throughput.
