If the degree distribution is chosen carefully, the irregular LDPC codes can outperform the regular ones. In this paper, we proposed an LDPC coded BICM scheme in image transmission system to improve both efficiency and reliability. Simulation results show that LDPC codes are good coding schemes over fading channel in image communication. Simultaneously, irregular codes can obtain a code gain of about 0.7 dB than regular ones when BER is 10-4. So the irregular LDPC codes are more suitable for image transmission than the regular codes.
