Simulation of Two-hop Relay Cooperative Communication Technology
Liu Ziyan · Communications technology · 2013
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.
