Summary: We consider the ensemble of low-density parity-check (LDPC) codes introduced by R. G. Gallager [IRE Trans. Inform. Theory IT-8, 21–28 (1962; Zbl 0107.11802)]. The Zyablov-Pinsker majority-logic iterative algorithm [V. V. Zjablov, M. S. Pinsker, Probl. Peredaci Inform. 11, No. 1, 23–26 (1975; Zbl 0358.94017)] for decoding LDPC codes is analyzed on the binary symmetric channel. An analytical lower bound on the error-correcting capability \(\tau _{\max}\) that grows linearly in the code block length is obtained.
