碩士 === 中原大學 === 電機工程研究所 === 106 === The new mobile network generation telecommunication 5G standard will provide a higher bandwidth at greater speeds. Within the proposed technology candidates, the most popular would be Non-orthogonal multiple access, NOMA. In a NOMA system, cell towers utilize the same frequency for multiplexing. By comparing different power levels and implementing Successive interference cancellation, SIC, more users can be serviced while effectively raising the spectral efficiency and system data transfer rate. In this thesis, we analyze the resource allocation in a downlink, SISO, NOMA system. Compare the data transfer rate between NOMA and OMA systems in a Nakagami-m fading channel environment. We also analyze both the power distribution in CR-NOMA and F-NOMA systems. The results from the simulation shows that NOMA systems performs better than OMA in terms of outage probability and system data transfer rate. The comparison between NOMA and OMA shows that NOMA provides more fairness. Another comparison of CR-NOMA and F-NOMA shows that CRNOMA has better interrupt performance.
