Abstract
In this paper, we proposed a construction of irregular QC-LDPC codes with improved approximated cycle extrinsic message degree (ACE) properties. The codes construct using the algorithm proposed have simple structure with good performance. Simulation results show that the proposed algorithm outperforms original PEG algorithm in the error-floor region.
