In the low-error rate regime, message-passing (MP) decoding for low-density parity-check
(LDPC) codes is known to have performance degradation due to trapping sets (TSs), which …

Trapping sets strongly degrade performance of low-density parity check (LDPC) codes in the
low-error-rate region. This creates significant difficulties for the deployment of LDPC codes …

This paper proposes a novel scheme for bit recovery of Low-Density Parity-Check (LDPC)
Codes. Firstly, the most erroneous and the most reliable bits are located by searching the …

Low-density parity-check (LDPC) codes are widely used in a variety of communication
systems because of their low complexity iterative decoding and performance approaching …

Low-Density Parity-Check (LDPC) codes have extensive applications in numerous
communication systems. However, iterative LDPC decoders may suffer from error floor. In …

Elementary trapping sets (ETSs) have been found to be the main cause of error floor in the
decoding of low-density parity-check (LDPC) codes. Moreover, irregular LDPC codes that …

Trapping sets with short cycles are known to give a detrimental effect on the error floor
performance of a low-density parity-check (LDPC) code. Unlike in binary LDPC codes., short …

The linear state-space model is a well-known code-independent method to estimate the
contribution of a trapping set (TS) structure to the error floor of low-density parity-check …

Trapping sets are considered the primary factor for degrading the performance of low-
density parity-check (LDPC) codes in the error-floor region. The effect of trapping sets on the …

In order to more exactly describe the errorfloor phenomenon in the iterative decoding of Low-
density parity-check (LDPC) codes, a modified concept of the stable trapping set is …
