Abstract: The Device-to-Device（D2D） communication can improve the utilization of spectrum resources and system throughput by reusing the resources of cellular users. However, it also brings severe co-channel interference to the system. In order to deal with the complex interference problem in the system and to improve the throughput of the system as much as possible under the condition that fairness of resource allocation, a resource allocation scheme based on fireworks algorithm is proposed. This paper aims for maximizing the weighted sum rate of the system, abstracts the resource allocation matrix into fireworks, and the final matching matrix is obtained by explosion, mutation and selection. Simulation results show that the proposed algorithm can effectively improve the throughput of the system and fairness of resource allocation.
