| Abstract: | The modification on the improved progressive-edge-growth(IPEG) algorithm is introduced in this paper,and the simulation of this algorithm is given based on the analysis of the algorithm.The advancements of the algorithm is increasing the connectivity of variable nodes using extrinsic message degree of variable nodes,which results in reducing the small stopping sets.Through computer simulation,the result shows that the codes constructed by the proposed algorithm have lower error floor than those constructed ... |
