Abstract(in English) | In this paper, we investigate the tightness of Tanner's lower bound for the minimum distance of regular low-density parity-check (LDPC) codes. More precisely, we introduce two classes of regular LDPC codes based on a combinatorial design known as Steiner system and we formulate Tanner's lower bound for these codes. Moreover, we point out that one of these two classes of codes contains EG-LDPC codes and show that Tanner's lower bound agrees with BCH bound for EG-LDPC codes. |
