摘要 中继(relay)技术是LTE-Advanced(LTE-A)系统中引入的关键技术之一,它能够改善通信链路的通信质量,提高系统容量和扩大小区覆盖范围。在此主要研究了LTE-A下行链路中基于两跳固定中继的协作通信技术,并以协作通信中常用的放大转发(AF,Amplify Forward)和译码转发(DF,DecodeForward)协作方式为重点,研究了引入中继节点(RN,Relay Node)后LTE-A系统中下行通信链路的性能,并对AF和DF两种协作方式进行了比较,由仿真结果可知在一定条件下DF协作方式的性能优于AF协作方式。 Relay, as one of the key technologies introduced in LTE-Advanced system, could improve the quality of communication link, raise the system capacity and expand the cell coverage. The cooperative communication technology based on fixed two-hop relay in LTE-A donw link is studied, and with AF and DF relay cooperative modes as the key points, the downlink-level performance of LTE-A system is discussed, the comparison of AF and DF relay cooperative technologies also done. Simulation indicates that the DF mode is superior to AF mode in performance.
