放大转发(Amplify Forward,AF)和译码转发(Decode Foward,DF)是中继协作通信技术中两种基本的中继协作方式。在研究两跳中继协作通信技术中AF和DF中继协作方式的基础上,针对基于门限的自适应中继协作方式,利用RN的位置信息提出了改进的自适应中继协作方式,并用蒙特卡洛方法对其仿真结果进行验证。结果表明所提出的改进自适应中继协作方式具有较好的协作性能。
AF and DF are two basic relay collaboration approaches in communication technology. AF and DF relay collaboration approaches in two-hop relay cooperative communication technology are researched on, and pro- posed an improved scheme that based on the threshold adaptive relay collaboration approach and the location infor- mation of the relay node, besides, the performance of the scheme was verified with Monte Carlo method. The result shows that the scheme achieved better cooperative performance.
