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 introduces the mapping method between link-level simulation and system-level simulation in OFDM system simulation, mainly discusses two methods based on effective SINR mapping: exponential effective SINR mapping (EESM) and mutual information effective SINR mapping (M I- ESM). This paper focuses on how these two methods transform the multi-state channel into a single-state channel and why such an effective single SINR method can represent the performance of multiple sub-carrier SINR channels. Meanwhile, the main advantages and disadvantages of the two methods as well as their impact on RRM The impact of algorithm design. Moreover, it also mentions how to construct link and system level mapping tables (MCS, SINR, BLER).
