Abstract :
We investigate suitable puncturing patterns for circulant sub-matrices based quasi-cyclic low-density parity-check codes whose binary base matrices have dual-diagonal parity structure with a single weight-3 column. The proposed method develops the existing puncturing criteria, and exploits the structure of the parity-check matrix. The performance of the proposed puncturing patterns is quite competitive with the performance of dedicated codes for individual rates
