Abstract: In order to reuse the spectrum resources and enhance system capacity, this paper proposes a novel radio resource allocation algorithm JOHG based on Joint Hungarian method.The presented algorithm can maximize transmission rate in heterogeneous network through the joint optimal allocation of spectrum resources and transmission power between D2D users and cellular users.Based on the association matrix, the Joint optimization problem is converted into a typical convex problem using the successive convex approximation.Simulation results show that the proposed algorithm can improve the overall performance of the system.
