Abstract

This paper presents sub-block design of low-density parity-check (LDPC) code as the efficient channel coding technique for JPEG image transmission over Rayleigh fading channel. 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 two different code rates of 0.769 and 0.935, and two different block sizes of 1057 and 4376. The performance of sub-block encoder design is evaluated by bit error rate (BER) improvement 50% and peak signal-to-noise ratio (PSNR) more than 30 at 8 dB SNR. ฉ 2012 IEEE.
