Abstract

In this paper, quasi-cyclic low-density parity-check (QC-LDPC) over additive white Gaussian noise (AWGN) channel for image transmission system is presented. The code is used as forward error correction (FEC) technique to protect transmitted source data over the channel. The sub-block encoder is designed with various AWGNs at three high rates QC-LDPC, 0.7294, 0.8438 and 0.9000. The performance of the proposed subblock encoder is evaluated by bit error rate (BER) improvement 13.5% and highest peak signal-to-noise ratio (PSNR) 33.7 at a low SNR.
