Trapping set structure of LDPC codes on finite geometries
2013 Information Theory and Applications Workshop (ITA)
The trapping set structure of LDPC codes constructed based on finite geometries, called finite geometry (FG) LDPC codes, is analyzed using a geometric approach. In this approach, trapping sets in the Tanner graph of an FG-LDPC code are represented by subgeometries of the geometry based on which the code is constructed. Using this geometrical representation, bounds and configurations of trapping sets of an FG-LDPC code can be derived and analyzed.doi:10.1109/ita.2013.6502951 dblp:conf/ita/DiaoTLA13a fatcat:nfcecz65kvcw3h6xd6zt33saca
