In this paper, we propose an approach to construct a class of irregular low-density parity-check (LDPC) codes based on row partition.We divide the rows of LDPC check matrix into subsets and derive an approach to arrange '1' in each column to prevent low weight code words.When decoded by iterative algorithm, the proposed codes show performance with low error floor and are subject to few undetected errors.The LDPC codes constructed based on the proposed scheme have efficiently encoding structures.
