摘要
Abstract
D2D(Device-to-Device)communication technology can effectively improve system throughput by multiplexing the channel resources of cellular users.However,when the D2D link pair reuses channel resources,it will cause the problem of co-channel interference between users.Therefore,in order to solve the interference problem between D2D users,base stations,and cellular users,an improved channel allocation algorithm based on a dual distance mechanism is proposed to allocate appropriate channel resources for D2D pairs.Then,according to the channel allocation results,a reasonable idle user is selected as a relay for each D2D pair to realize Device-to-Device relay communication.The simulation results show that the algorithm can effectively im-prove the throughput of the communication system.关键词
