ABSTRACT:
A system and method for the resynchronization of a sequential decoder that decodes received signal samples stored within an input buffer is disclosed. The system comprises two auxiliary decoders coupled to the sequential decoder for running a simplified MAP decoding process when the input buffer reaches a threshold saturation level. Control of the respective increments of a read pointer and a write pointer allows one to detect the saturation of the input buffer and to derive a sequence of signal samples to the appropriate auxiliary decoder. The selected auxiliary decoder estimates a resynchronization state for the sequential decoder based on the sequence of signal samples. According to the read and the write pointers value, normal sequential decoding is resumed, otherwise, the second auxiliary decoder is selected. The selected auxiliary decoder estimates a resynchronization state for the sequential decoder based on a new sequence of signal samples.
