Abstract
A novel joint source/channel image coding algorithm for image transmission system was proposed. The proposed algorithm is based on the best wavelet packet in a rate-distortion sense. Because of the noise in transmission channel, the channel and the channel code information had been introduced to the source image coding. The image coding is based on wavelet packet, and a bit plane coding algorithm have been used for the wavelet packet sub-band coding, so the coded bit streams can be match to UEP transmission by WICP-LDPC code. The simulation results in BSC channel show that, the proposed algorithm is better than the EEP and several other image transmission algorithms.
