A pre-encoding apparatus and a pre-decoding apparatus are provided. The pre-encoding apparatus adopts a cascade structure constituted by a plurality of pre-encoding units and a plurality of interleavers for pre-encoding, and the pre-decoding apparatus adopts a cascade structure constituted by a plurality of pre-decoding units and a plurality of de-interleavers for pre-decoding. Therefore, the pre-decoding apparatus is featured with a lower error rate. Also, each of the pre-decoding units can be alternatively composed of a plurality of low dimensional pre-decoders so that a computation complexity of the pre-decoding apparatus can be reduced accordingly.
