Controlling the Error Floor in LDPC Decoding
Shuai Zhang, Christian Schlegel
The error floor of LDPC is revisited as an effect of dynamic message behavior in the so-called absorption sets of the code. It is shown that if the signal growth in the absorption…

On the Dynamics of the Error Floor Behavior in (Regular) LDPC Codes
Christian Schlegel, Shuai Zhang
It is shown that dominant trapping sets of regular LDPC codes, so called absorption sets, undergo a two-phased dynamic behavior in the iterative message-passing decoding algorithm.…
