Abstract

The present disclosure provides an evaluation unit which includes a central data-processing unit, at least one storage unit and an allocation unit, wherein the allocation unit and the at least one storage unit (3) are connected to the central data-processing unit. The central data-processing unit loads at least one OFDM signal from the at least one storage unit and transfers this to the allocation unit. The allocation unit displays the individual signal spaces of the OFDM symbols of the at least one OFDM signal in a constellation diagram and in a frame-output matrix in such a manner that it is possible to allocate via the diagrams at which signal spaces data symbols and/or pilot symbols and/or zero symbols and/or don't care symbols are present and with which modulation type the data symbols and/or pilot symbols are modulated.
