The design of GLDPC codes for the binary erasure channel with low error floor under iterative decoding is investigated. Both bounded distance and maximum a posteriori decoding at the check nodes are considered. For both check node decoding algorithms a key para- meter is identified, discriminating between an exponen- tially small and exponentially large expected number of small size stopping sets. A code design technique is proposed based on this theoretical investigation.

Abstract
The design of GLDPC codes for the binary erasure channel with low error floor under iterative decoding is investigated. Both bounded distance and maximum a posteriori decoding at the check nodes are considered. For both check node decoding algorithms a key para- meter is identified, discriminating between an exponen- tially small and exponentially large expected number of small size stopping sets. A code design technique is proposed based on this theoretical investigation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
