Abstract
A syndrome assisted iterative decoder ( ) uses iterative processing to decode an input sequence. A syndrome-assisted decoder ( ), which may operate independently of a soft-output decoder, provides a stopping algorithm for the soft output decoder ( ). When the syndromes s and s generated for sequence v and v , respectively, both equal 0, the soft output decoder is finished decoding the sequence of data. Additionally, the syndrome-assisted decoder can generate a modified error trellis used by the soft output decoder whereby the soft-output decoder operates on a simplified trellis providing improved decoder performance.
