The present decoding technique provides an efficient technique for
decoding linear block codes from multiple encoders. When an error in a
code sequence is detected, the decoding technique estimates a confidence
for each bit within the code sequence. Based on the confidence, a subset
of bits within the code sequence is obtained. The subset of bits is then
incrementally flipped to determine a set of modified code sequences. A
syndrome is computed for each of the modified code sequences based on a
preceding computed syndrome and an update vector.
