A decoding apparatus in an Orthogonal Frequency Division Multiple Access (OFDMA) mobile communication system is provided. In the apparatus comprises, a first combiner performs first combining on an input burst a first number of times. A deinterleaver deinterleaves an output of the first combiner and outputs a burst having a repeated structure. A second combiner performs second combining on the burst having the repeated structure a second number of times. A decoder decodes the combined burst. A signal detector stores a second internal memory state value of the decoder for an instance where a first decoded bit is extracted from the decoded data, stores a second internal memory state value of the decoder for an instance where a last decoded bit is extracted from the decoded data, compares the first and second stored internal memory state values of the decoder, and sets a burst quality indicator (BQI) according to the comparison result.
