A rate allocation (RA) method in joint source/channel coding for transmission of images over varying channels with Markov model is proposed, in which the dependency of channel states during transmission of image packets is considered. For rate allocation (RA) problem, a weighted packet decoding error probability (PDEP) approximation method is presented. Our simulations show that the proposed RA method leads to a better performance over existing RA policies.
