Abstract :
Progressive edge-growth (PEG) algorithm is a good candidate to generate tanner graphs with a large girth by establishing edges or connections between symbol and check nodes in an edge-by-edge manner. In this paper, we propose an extended PEG algorithm for constructing low-density parity-check (LDPC) codes with very high rate when given a lower bound of girth. Simulation results show the bit error rates of constructed LDPC codes with very high rate or large girth.
