In this paper we propose to use a self-correction technique with two computationally efficient LDPC decoding algorithms: QRCBP and adjusted min-sum. It is shown that using such a technique allows to improve performance of this algorithms both in error floor and waterfall regions. Also comparison with other BP-based simplified decoding algorithms is presented for three quasi-cyclic LDPC codes.
