| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系 === 106 === Introducing the D2D communication into the cellular network, especially 5G mobile system, can greatly improve the system performance not only in operation interest and also for user experiences. Therefore, related studies have drawn much attention in recent years. However, adding D2D communication to the mobile cellular network will increase much more complex interference and user-side battery life problems. In this thesis we aim to propose a joint resource allocation algorithm to maximize the energy efficiency of D2D communication system. It is mainly carried out in three steps. In the first step, the overall system model will be simplified by limiting the interference range based on the constraints of minimum transmission rate; In the second step, we apply the Dinkelbach algorithm to solve problem of maximize each D2D link energy efficiency; In the third step, We exploit The KM algorithm to allocate cellular user spectrum resource to D2D user so that total energy efficiency of all D2D links can be maximized. The simulation results have shown the excellence of our scheme.
