This paper proposes optimal image transmission over coded Orthogonal Frequency Division Multiplexing system with Low Density Parity Check Coding. The DWT based Set Partitioning in Hierarchical Trees algorithm is used for source coding of the images to be transmitted. It improves the transmission efficiency for progressive image transmission over Additive White Gaussian Noise channel. Study Work and MATLAB simulation results show that, gradual increase in visual quality of reconstructed images and performance of the PAPR of OFDM for different SPIHT rates.
