On the Convergence Speed of Spatially Coupled LDPC Ensembles Under Window Decoding
Qingqing Peng, Dongxu Chang, Guanghui Wang +1
It is known that windowed decoding (WD) can effectively balance the performance and complexity of spatially coupled low-density parity-check (LDPC) codes. In this study, we show th…
Dynamic Layered Decoding Scheduling for LDPC Codes Aided by Check Node Unsatisfied Probabilities
Chenyuan Jia, Dongxu Chang, Ruiyuan Wang +3
This letter revisits update ordering in layered belief propagation (LBP) decoding of low-density parity-check (LDPC) codes. The closest probability-based schedule orders layers by…
High Throughput QC-LDPC Decoder With Optimized Schedule Policy in Layered Decoding
Dongxu Chang, Qingqing Peng, Guanghui Wang +1
In this study, a scheduling policy of layered decoding for quasi-cycle (QC) low-density parity-check (LDPC) codes with high throughput and good performance is designed. The influen…
