These requirements were identified in the Industry 4.0 (I4.0) initiative as well as in 5th Generation (5G) mobile communication standardization where polar codes are selected to meet Ultra Reliable Low Latency Com- munication (URLLC) requirements. Accurate link abstraction models of those systems are required for system level simulations. However, it is uncertain how short, polar-coded packets with Bit- Interleaved Coded Mapping (BICM) in Orthogonal Frequency Division Multiplexing (OFDM) systems at low Frame-Error- Rates (FERs) can be characterized via Effective SNR Mapping (ESM). We investigate if and how short packet communication systems with polar codes can be modeled accurately via ESM methods. We compare new error measures for FER curve fitting in order to find optimal ESM adjustment factors for low FERs. We present simulation results that show how susceptible adjustment factors are to different system parameters. Finally, we demonstrate that accurate link abstraction is possible for the target system even at the desired working point.}, booktitle={12th International ITG Conference on Systems, Communications and Coding 2019} }
