Research on the Method of Enhancing the User Capacity of Dense User Asynchronous Frequency Hopping Networks Based on NOMA Technology

This paper proposes a scheme based on NOMA (Non-Orthogonal Multiple Access) to enhance user capacity in asynchronous frequency hopping networks, which is limited by available frequency resources. By reusing frequency resources among multiple nodes, NOMA technology can effectively reduce the number of frequency resources required by users in accessing network, thereby improving spectrum utilization and significantly increasing user capacity. This article proves by simulation that the asynchronous frequency hopping network based on NOMA has higher user capacity in intensive multi-user scenarios.
