the 4-state Markov model is made as the long-bursting error possibility model of mobile channels
and punctured convolutional codes (PCC) are applied to 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 different code rates
constraint lengths of mother codes and interleaving degrees.Simulation results show the superiority of UEP directy.
