Abstract: A signal processing device includes a determiner configured to determine if a codeword included in a data signal corresponds to a reference codeword included in a first set of reference codewords or a second set of reference codewords; a first estimator configured to estimate a first channel quality metric value for the data signal based on a first channel quality metric, if the codeword corresponds to a reference codeword included in the first set of reference codewords, wherein the first channel quality value is smaller than a reference channel quality metric value for the data signal, wherein the reference channel quality metric value for the data signal results from a channel quality estimation based on a predetermined channel quality metric; and a second estimator configured to estimate a second channel quality metric value for the data signal based on a second channel quality metric, if the codeword corresponds to a reference codeword included in the second set of reference codewords, wherein the second channel quality value is equal to or larger than the reference channel quality metric value for the data signal.
