چکیده
This work 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. Keywords-AWGN, DWT, LDPC, OFDM, SPIHT .

Proposed Pilot Pattern Methods for Improvement DVB-T System Performance
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
