Turán-Theoretic Bounds on Several Elementary Trapping Sets in LDPC Codes
Ziyang Zhao, Haoran Xiong, Zicheng Ye +2
LDPC codes have attracted significant attention due to their capacity-approaching performance. Elementary trapping sets are the main cause of the error floor phenomenon in LDPC cod…
The Impact of the Distance Between Cycles on Elementary Trapping Sets
Haoran Xiong, Guanghui Wang, Zhiming Ma +1
Elementary trapping sets (ETSs) are the main culprits of the performance of low-density parity-check (LDPC) codes in the error floor region. Due to their large quantities and compl…
On the lifting degree of girth-8 QC-LDPC codes
Haoran Xiong, Guanghui Wang, Zhiming Ma +1
The lifting degree and the deterministic construction of quasi-cyclic low-density parity-check (QC-LDPC) codes have been extensively studied, with many construction methods in the…
Theoretical Bounds for the Size of Elementary Trapping Sets by Graphic Methods
Haoran Xiong, Zicheng Ye, Huazi Zhang +6
Elementary trapping sets (ETSs) are the main culprits for the performance of LDPC codes in the error floor region. Due to the large quantity, complex structures, and computational…
