An Improved ACE Algorithm Based on Structural Optimization LDPC
Wang Li · Journal of Henan University of Science & Technology · 2010
In order to improve the performance of LDPC code,an optimized LDPC code was constructed by calculating extrinsic message degree of the cycle.This algorithm can remove the short cycle,which is produced unavoidably in constructing LDPC codes,to improve a bipartite graph local connectivity.Experimental results show that the algorithm is better to improve LDPC codes' performance in the same code length,code rate and the degree distribution.
