−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders at low error rates. Past experiments h...
Low-density parity-check codes using the beliefpropagation decoding algorithm tend to exhibit a high error floor in the bit error rate curves, when some problematic graphical stru...
Abstract— In recent years performance prediction for communication systems utilizing iteratively decodable codes has been of considerable interest. There have been significant b...
Abstract— There is a well-known error-floor phenomenon associated with iterative LDPC decoders which has delayed the use of LDPC codes in certain communication and storage syste...
Assuming iterative decoding for binary erasure channels (BECs), a novel tree-based technique for upper bounding the bit error rates (BERs) of arbitrary, finite low-density parity-c...
