摘　　要：介绍了在OFDM系统仿真中链路级仿真和系统级仿真之间的映射方法,主要探讨了两种基于有效SINR映射的方法:指数有效SINR映射(EESM)和互信息有效SINR映射(M I-ESM)。着重阐述了这两种方法如何把多状态信道变成单状态信道以及为什么这种有效单SINR方法能够表示多个子载波SINR信道性能,同时也重点研究这两种方法的主要优缺点以及它们对RRM算法设计的影响。而且,也提及了如何去构建链路和系统级映射表(MCS,SINR,BLER)。This paper presents the approaches of link to system mapping for OFDM/muhi -carrier mobile communication system by analysing some materials. Mainly, the effective SINR method is highlighted, which includes EESM and MI - ESM. It shows how the multi - state channels are integrated into a single state in system simulator with effective SINR approach and why the effective SINR can represent the performance of multiple sub - carrier S1NR. It also discusses what the main advantages and disadvantages for them are and how they can influence on the RRM design of the systems. Furthermore, indication will be given of how to construct a link - to - system mapping table （MCS, SINR, BLER）.
