| Zusammenfassung: | Methods, systems, and computer readable media can be operable to calculate modulation error ratio using feedback from error correction processing. An error correction value obtained through an error correction process can be added to a measured slicer error in order to calculate a modulation error ratio. An error correction value associated with a correctable error can be based upon the difference between a received symbol and a correct symbol. An error correction value associated with an uncorrectable error can be based upon a measured slicer error and the distance between constellation symbols in a constellation diagram. |
