Improved progressive-edge-growth (PEG) construction of irregular LDPC codes
IEEE Communications Letters , Volume 8 - Issue 12 p. 715- 717
Progressive-edge-growth (PEG) algorithm is known to construct low-density parity-check codes at finite block lengths with very good performance. In this letter, we propose a very simple modification to PEG construction for irregular codes, which considerably improves the performance at high signal-to-noise (SNR) ratios with no sacrifice in low-SNR performance.
