Abstract
A decoding apparatus and method for estimating a reliability value by detecting uncorrected packet errors. The decoding apparatus includes a hard-decision unit and a reliability determination unit. The hard-decision unit performs hard-decision on a soft-input of a code. The reliability determination unit generates a reliability estimation value of the hard-decision result according to whether a packet error exists in the hard-decision result. The hard-decision unit performs hard-decision in response to the reliability estimation value.
