Optimal Progressive Image Transmission Over Rayleigh Fading Channels


Ahmad Hatam, Ali M. Doost-Hoseini


Vol. 10  No. 7  pp. 245-252


A fixed-packet optimal joint source channel coding scheme for transmission of progressive images over Rayleigh channels is proposed. A first order Markov model is used in rate allocation problem to concern channel temporal variations during image transmission. Also, introducing a modification on the used progressive coding scheme, the requirement for the immediate decoding termination upon the observation of an erroneous packet is relatively relaxed. A rate allocation mechanism for this modified version of progressive codes is also proposed.
