Research And Simulation Of Rela Y Coordination For Green Commu Nication

Green communication is not only an important direction of current wireless communication research,but also a popular research topic.Through the green communication research,we can effectively reduce energy consumption and improve resource utilization.This thesis focuses on the energy efficiency optimization and resource optimization of the two-way relay collaboration model.Two-way relay collaboration technology is the mainstream of the current network operation technology,as it is in line with the current research mainstream with practical significance and value.This thesis first investigates the development of current communication,analyzes the importance of green communication,and selects the relay collaboration technology as the entry point,investigates and understands the development history and research status of relay communication technology,and establishes research topics and research contents.Then,the green communication technology is discussed in details,and the wireless communication characteristics and green communication technology are discussed respectively.The detailed analysis of the relay cooperation protocol and the relay collaboration system type is carried out,and the forward amplification is selected based on the green communication requirements.Two-way relay system is used as the basic model of this research.Then,based on the most simplified three-point relay system for multi-dimensional research,the relevant algorithms on the communication efficiency,energy efficiency,stability and three dimensions of power distribution are put forward.Finally,we chose the more complex OFDM bi-directional multi-carrier multi-relay system to carry out more in-depth joint resource optimization research,proposed BOMHM algorithm strategy to complete the optimal relay selection strategy,which achieved the goal of green communications through the joint resource optimization between the resource selection and the integration of resources.In this thesis,based on green communication study,we select the relay collaboration technology as a starting point.From the basic system and protocol selection,to the minimum system model of power distribution,and then to the complex multi-carrier multi-relay system joint resource optimization research,the thesis put forward the application of different power distribution methods OPA.The simulation was done to verify the performance of the selection method BOMHM and bit allocation strategy ABAA.The results show that they can effectively reduce energy consumption and improve resource efficiency to achieve green communication.
