Construction of High-Rate Regular Quasi-Cyclic LDPC Codes Based on Cyclic Difference Families
Hosung Park, Seokbeom Hong, Jong-Seon No +1
For a high-rate case, it is difficult to randomly construct good low-density parity-check (LDPC) codes of short and moderate lengths because their Tanner graphs are prone to making…
Design of Multiple-Edge Protographs for QC LDPC Codes Avoiding Short Inevitable Cycles
Hosung Park, Seokbeom Hong, Jong-Seon No +1
There have been lots of efforts on the construction of quasi-cyclic (QC) low-density parity-check (LDPC) codes with large girth. However, most of them are focused on protographs wi…
Fast Correlation Computation Method for Matching Pursuit Algorithms in Compressed Sensing
Kee-Hoon Kim, Hosung Park, Seokbeom Hong +2
There have been many matching pursuit algorithms (MPAs) which handle the sparse signal recovery problem a.k.a. compressed sensing (CS). In the MPAs, the correlation computation ste…
New decoding scheme for LDPC codes based on simple product code structure
Beomkyu Shin, Seokbeom Hong, Hosung Park +2
In this paper, a new decoding scheme for low-density parity-check (LDPC) codes using the concept of simple product code structure is proposed based on combining two independently r…
