| Abstract(in English) | Non-Orthogonal Multiple Access (NOMA) is a promising next-generation communication technology that enables multiple terminals to use the same frequency band, leading to enhanced frequency utilization efficiency. Since NOMA is based on multiplexing in the power domain, user pairing is crucial in maximizing overall system throughput. However, since the number of possible pairings increases dramatically in double factorial order on the number of terminals, obtaining an optimal pairing in an instantaneous manner is not easy. This study applied a heuristic efficient pairing algorithm, wherein pairing optimization is transformed to a traveling salesman problem in a three-layer graph structure, to the pairing problem in NOMA assuming a realistic radio environment. We examined the performance, including comparisons to conventional methods. |
