Abstract: A soft demapping apparatus and method thereof includes a pre-processing unit to pre-process a reception signal obtained from a symbol representing bits. A candidate selection unit selects two candidates from among constellation points included in a constellation for each of the bits. A distance calculation unit calculates a Euclidean distance between the reception signal and the two candidates. A log-likelihood ratio (LLR) calculation unit calculates an LLR with respect to the bits based on the Euclidean distance between the reception signal and the two candidates.
