Iterative decoder employing multiple external code error checks to lower the error floor and/or improve decoding performance. Data block redundancy, sometimes via a cyclic redundancy check (CRC) or Reed Solomon (RS) code, enables enhanced iterative decoding performance. Improved decoding performance...http://www.google.de/patents/US7568147?utm_source=gb-gplus-sharePatent US7568147 - Iterative decoder employing multiple external code error checks to lower the error floor
