PROJECT TITLE :

Power Allocation Study for Non-Orthogonal Multiple Access Networks With Multicast-Unicast Transmission - 2018

ABSTRACT:

This Project considers a downlink single-cell non-orthogonal multiple access (NOMA) network, where the base station, that has multiple antennas, broadcasts the mixed multicast and unicast messages to multiple users with a single antenna. We tend to propose two sorts of power allocation schemes for NOMA networks with multicast-unicast transmission to research the impact of performance, particularly, cognitive radio inspired NOMA with dynamic quality of service (QoS) at multicast users (CR-NOMA-D-M), and CR-NOMA constrains the dynamic QoS at the unicast user (CR-NOMA-D-U). Based mostly on the proposed schemes, we drive the exact/closed-kind expressions for the secrecy outage probability, outage chance, as well because the approximate outage chance at high signal-to-noise ratio to review the range gain. Compared with existing works, the derived analytical results show that each proposed schemes cannot solely considerably improve the outage performance for multicast users, but additionally remarkably enhance the diversity gain and therefore the secrecy outage likelihood for the unicast user. Finally, the theoretical results are validated by the numerical results.
