1. An iterative decoder, comprising:

  • an internal code decoder operable to perform iterative decoding of a data block; and

    an external code decoder capable of supplying a feedback signal to the internal decoder wherein the feedback signal is used to influence selective decisions during subsequent decoding iterations of the data block, wherein the influence of the feedback signal comprises a path restriction mechanism that prohibits a plurality of undesirable outcomes from occurring during the iterative decoding of the data block.
