Summary:
In this study, we investigate a method for fast optimizing the resource allocation problem in non-orthogonal multiple access (NOMA) using a Coherent Ising Machine (CIM), a type of Ising Machine. The CIM is a hardware capable of obtaining fast solutions to the Ising problem. In order to perform NOMA resource allocation using CIM, the data rate maximization problem in NOMA systems is transformed into the Ising problem. The formulation for stable operation on the actual CIM machine is also discussed. Simulation results show that the proposed method is superior not only speed of optimization but also reaching the optimal solution.
