Abstract: Aiming at the shortcomings of current resource allocation strategy of multiuser system, such as poor user fairness and small system throughput, we designed a resource allocation strategy of multiuser system based on artificial fish swarm algorithm. Firstly, by analyzing the working  principle of resource allocation of multiuser system, we constructed the corresponding mathematical model. Secondly, we introduced the artificial fish swarm algorithm to solve the mathematical model of the resource allocation of multiuser system, and improved the limitations of the standard artificial fish algorithm. Finally, the simulation and comparative test experiments were carried out  with other resource allocation strategies of multiuser system. The experimental results show that the artificial fish swarm algorithm can quickly and accurately find the optimal allocation scheme of multiuser system resources. It can effectively protect the fairness of the users, and greatly improve the communication ability of the multiuser system. The overall performance is superior to the other resource
 allocation strategies of multiuser system.
