1. An error-correcting serial turbo-decoder comprising:
an input configured to receive a word to be decoded comprising intrinsic information items pertaining to useful data, external and internal redundancy data,
at least one internal decoder configured to implement a SISO (Soft-In Soft-Out) algorithm and
an external decoder configured to implement a SISO (Soft-In Soft-Out) algorithm;
one of the internal decoders and the external decoder being configured to receive in parallel the intrinsic information items of the channel pertaining to a word to be decoded at the start of each decoding cycle;
the internal decoder being configured to carry out a part of the decoding of the word based on the intrinsic information items pertaining to the useful data, and the internal and external redundancy data,
the external decoder being configured to carry out another part of the decoding of the word based on the intrinsic information items pertaining to the useful data and the external redundancy data.
