摘要：
Provided is a soft demapping apparatus that may detect a log likelihood ratio (LLR) value of a quadrature amplitude modulation (QAM) signal, using a shifted table scheme, may designate a sub-region of the QAM signal corresponding to bit information that is obtained by decoding the LLR value, and may calculate an LLR value of other bit information included in the designated sub-region.
