Abstract

In this paper, the 4-state Markov model is presented as a long-burst error probability model of a mobile channel, and punctured convolutional codes (PCC) are applied to an image transmission system over mobile fast-fading channels. We propose a new scheme of unequal error protection (UEP) in image transmission by means of adjusting the different code rates, the constraint length of the mother code and interleaving degree. Simulation results show the superiority of UEP directly
