Density Evolution Analysis of Generalized Low-density Parity-check Codes under a Posteriori Probability Decoder
Dongxu Chang, Qingqing Peng, Zhiming Ma +2
In this study, the performance of generalized low-density parity-check (GLDPC) codes under the a posteriori probability (APP) decoder is analyzed. We explore the concentration, sym…
On the Performance of Low-complexity Decoders of LDPC Codes
Qingqing Peng, Dawei Yin, Dongxu Chang +4
Efficient decoding is crucial to high-throughput and power-sensitive wireless communication scenarios. A theoretical analysis of the performance-complexity tradeoff toward low-comp…
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…
An Optimization Model for Offline Scheduling Policy of Low-density Parity-check Codes
Dongxu Chang, Zhiming Ma, Guanghui Wang +2
In this study, an optimization model for offline scheduling policy of low-density parity-check (LDPC) codes is proposed to improve the decoding efficiency of the belief propagation…
