Finite-Dimensional Bounds on Zm and Binary LDPC Codes with Belief Propagation Decoders
Chih-Chun Wang, Sanjeev R. Kulkarni, H. Vincent Poor
This paper focuses on finite-dimensional upper and lower bounds on decodable thresholds of Zm and binary low-density parity-check (LDPC) codes, assuming belief propagation decoding…
Exhausting Error-Prone Patterns in LDPC Codes
Chih-Chun Wang, Sanjeev R. Kulkarni, H. Vincent Poor
It is proved in this work that exhaustively determining bad patterns in arbitrary, finite low-density parity-check (LDPC) codes, including stopping sets for binary erasure channels…
Code Annealing and the Suppressing Effect of the Cyclically Lifted LDPC Code Ensemble
Chih-Chun Wang
Code annealing, a new method of designing good codes of short block length, is proposed, which is then concatenated with cyclic lifting to create finite codes of low frame error ra…
Upper Bounding the Performance of Arbitrary Finite LDPC Codes on Binary Erasure Channels
Chih-Chun Wang, Sanjeev R. Kulkarni, H. Vincent Poor
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…
Density Evolution for Asymmetric Memoryless Channels
C. -C. Wang, S. R. Kulkarni, H. V. Poor
Density evolution is one of the most powerful analytical tools for low-density parity-check (LDPC) codes and graph codes with message passing decoding algorithms. With channel symm…
On the Typicality of the Linear Code Among the LDPC Coset Code Ensemble
Chih-Chun Wang, H. Vincent Poor, Sanjeev R. Kulkarni
Density evolution (DE) is one of the most powerful analytical tools for low-density parity-check (LDPC) codes on memoryless binary-input/symmetric-output channels. The case of non-…
