Industrial radio communication systems spawn a

new set of requirements for wireless communication systems

with high reliability and low latency. 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.
