Comparative Study of Fairness and Fixed Power Allocation Algorithms : in Non-Orthogonal Multiple Access System
International Symposium on Image and Signal Processing and Analysis(2022)
摘要
Non-orthogonal multiple accesses (NOMA) is one of advanced technologies which is used to improve the quality of service in fifth generation systems. Furthermore, it increases the capacity, massive connectivity, enhanced data rate, reduced latency, and minimizing the required spectrum bandwidth. On the other hand, NOMA is characterized by some disadvantages specially the problem of consuming high power allocation from the users. For this reason, the community of the researchers in the wireless communication domain has been developed two techniques such as: the fix and the fair power allocation. In this paper, we compare the sum rate of the fair Power Allocation with the fixed Power allocation algorithm in downlink NOMA systems. Preliminary simulation results have been achieved to confirm that the dynamic fairness power allocation can be useful to perform high sum rate than the fixed power allocation.
