| Abstract: | Based on the research of user equipment relay, a formula of link capacity is induced on the amplify and forward （AF）cooperative receive diversity relay mode. An algorithm for joint relay selection and resource allocation is proposed according to the distribution of idle users. Simulation results show that the algorithm can increase the system capacity and improve the throughputs of cell-edge user links. |
