Abstract(in Japanese) (See Japanese page)
Abstract(in English) Non-orthogonal multiple access (NOMA) is a technology that allows multiple users to share the same channel with appropriate power and channel allocation at the transmitter, which is then decoded at the receiver. Faster channel allocation in NOMA is necessary to maintain optimal performance in a dynamic environment. Previous research has shown that the Laser Chaos Decision-Maker solves ultra-fastly the multi-armed bandit problem which is one of the decision-making problems. However, as the number of users increases, the complexity of channel allocation increases rapidly, making it challenging to achieve appropriate channel allocation using the single Laser Chaos Decision-Maker method from previous research. Therefore, we propose a parallel structure of Laser Chaos Decision-Makers to determine the channel for each user. By using this parallel structure, the proposed method can achieve effective and ultra-fast channel allocation regardless of the number of users. Simulation results show that our proposed method can achieve higher total data rates than C-NOMA and UCGD-NOMA in multiple wireless communication environments with varying densities and distance attenuation.
