Non-Binary LDPC Codes Design Based on Euclidean Geometries
Guihua Zeng · Computer Knowledge and Technology · 2010
This paper presents a Euclidean geometric approach to the construction of Non-Binary low-density parity-check(LDPC) codes.Codes of this class have girth at least 6.They perform very well with iterative decoding.Furthermore,these codes can be decoded with simple shift registers,with linear complexity and decoded in the semi-parallel way.The simulation results show that their performance is much better than the binary LDPC codes.
