	Get an output for the decoding error probability of a given transport block. This method is not purely virtual. If derived ErrorModel does not override, the MIMO matrix is converted to a linear SpectrumValue, and the non-MIMO method is called.

Detailed Description

This class provides the BLER estimation based on mutual information metrics, assuming TC coding with block segmentation as per TS 36.212 Sect. 5.1.2 and modulation and coding in TS 36.214 including up to 64-QAM. The BLER-SINR curves are obtained from a link level simulator (Vienna) that uses TC coding and said MCSs. In case of HARQ, the model currently follows HARQ with Incremental Redundancy, so that both the ECR and the MI are updated based on IEEE 802.16m-08/004r2.

Introspection did not find any typical Config paths.
No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 56 bytes (on a 64-bit architecture).
