A Modified PEG Algorithm for Construction of LDPC codes with Polynomial of Cycle

摘要：

Progressive Edge-Growth (PEG) algorithm is a novel approach for construction of low-density parity-check (LDPC) codes with large girth. However, PEG algorithm ignores the effect of the number of shortest cycles. In this paper, we propose a modified PEG algorithm with Polynomial of Cycle, which achieves not only large girth, but also minimizes the number of shortest cycles significantly. Simulation results show that our proposed algorithm can improves the performance of LDPC codes.
