We propose a complexity-reducing algorithm for serial min-sum
decoding that reduces the number of check nodes to process
during an iteration. The check nodes to skip are chosen
based on the reliability, a syndrome
and a log-likelihood-ratio (LLR) value, of the
incoming messages.
The proposed algorithm is evaluated by computer simulations
and shown to reduce the decoding complexity about 20%
compared with conventional serial min-sum decoding with
small fractional decibel degradation in error correction
performance. |
