Application of Low-density Parity-check (LDPC) codes and orthogonal frequency division multiplexing (OFDM) modulation technology were studied in the image transmission, and the effect of three kinds of different LDPC codes and OFDM modulation technology on the image transmission over wireless fading channel was studied and simulated. The simulation results show that the combination of LDPC codes and OFDM modulation technology can obtain image transmission with high speed and high bandwidth efficiency, which can solve the problems about transmission speed and efficiency caused by mass image data. The image transmission with high speed and high spectral efficiency and can be achieved.
