Multiple decoding method for turbo and ldpc decoders, and apparatus thereof

Disclosed are a multiple decoding method for a turbo and an LDPC decoder, and an apparatus thereof. A multiple decoding apparatus according to an embodiment of the present invention comprises: a plurality of unit decoding units including a plurality of check node computation units for low density parity check (LDPC) decoding, a plurality of bit node computation units, and a plurality of decoders for turbo decoding configured to share a common computation unit performing common computation with each of the node computation units; a mode selection unit for receiving a mode selection signal for selecting one of the turbo decoding and the LDPC decoding; a plurality of interleaving control units for, on the basis of the mode selection signal, interleaving one output value of a plurality of decoders of the preceding unit decoding units in the plurality of unit decoding units adjacent to each other and selectively outputting the interleaved output value to one of a plurality of decoders of the succeeding unit decoding units; and a plurality of deinterleaving control units for, on the basis of the mode selection signal, deinterleaving one output value of the plurality of decoders of the subsequent unit decoding units and selectively outputting the deinterleaved output value to one of a plurality of decoders of the preceding turbo decoding unit.
