Instanton analysis of Low-Density-Parity-Check codes in the error-floor regime
Abstract-- In this paper we develop instanton method introduced in [1], [2], [3] to analyze quantitatively performance of Low-Density-Parity-Check (LDPC) codes decoded iteratively ...

Analysis of Absorbing Sets for Array-Based LDPC Codes
— Low density parity check codes (LDPC) are known to perform very well under iterative decoding. However, these codes also exhibit a change in the slope of the bit error rate (BE...

Searching for low weight pseudo-codewords
— Belief Propagation (BP) and Linear Programming (LP) decodings of Low Density Parity Check (LDPC) codes are discussed. We summarize results of instanton/pseudo-codeword approach...
