A syndrome assisted iterative decoder (173) uses iterative processing to decode an input sequence. A syndrome-assisted decoder (216), which may operate independently of a soft-output decoder, provides a stopping algorithm for the soft output decoder (240). When the syndromes s0 and s1 generated for sequence v0 and v1, 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.
