Improved Progressive-Edge-Growth (PEG) Construction of Irregular LDPC Codes
H. Xiao, Amir H. Banihashemi · IEEE Communications Letters · 2004
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.
