摘要：
A decoding device includes a BM calculator calculating a branch metric in a Log-MAP algorithm from received data and extrinsic information, an ACS operator calculating a maximum value of a path metric based on the branch metric, a correction term calculator calculating a Jacobian correction value of the path metric, and a correction operator correcting the path metric by adjusting a value of the Jacobian correction value based on a size of the received data and adding the adjusted correction value to the maximum value.
