AiWract-In this paper, we apply a new erroreorrecting code - lowdensity parily-check (LDPC) code aa the efficient channel coding technique in image commmnkation on Rayleigh fading channel. The LDPC schemes with two different code lengths and two different code rates are simulated. Results show that LDPC codes have very good performance in image recovering over Rayleigh fading channel. By using a regular LDPC code with parameter R4/2 and N32048, the image can be recovered perfectly at about 55dB with rather low time delay and system complexity.
