Abstract
The co-channel interference caused by the resource reuse of the full-duplex D2D and the residual self-interference will greatly degrade the performance of the 5G system.Therefore,this paper proposed a power control scheme.It obtained the optimal transmit power through the Lagrangian duality method of convex programming to maximize the link rate of the full-duplex D2D and met the QoS requirements of the cellular users.The simulation shows the difference half-duplex D2D and fullduplex D2D gain with the changes about the needs of cellular users and the self-interference cancellation,and the performance of the full-duplex D2D multiplex with different numbers of channels.关键词
