In this paper, we adopt the (2, 1, 3) convolutional code combined with interleaving technique as the anti-interference measure. We simulate and discuss the performance of error-correcting of a standard image transmitted through totally eight mobile channels which have four different modulation styles and two different vehicle speeds and we also compare the performance with that in an AWGN channel. We study the influence of the fast-fading character to the reliability of image transmission, the error-correcting performance of the convolutional codes in mobile channel and the significance of the interleaving technique. At the same time we prove the results we've got are similar to that we'd done previously, we obtain some significant conclusions and propose some idea for the image mobile communication system.

Based on the idea of unequal error protection, a novel error-correcting scheme for variable-length codes (VLC) is proposed. The synchronisation information in the VLC-coded bitstream acquires more protection without increasing coding overhead. Simulation results exhibit considerable gains of the proposed scheme over the traditional error-correcting scheme under a wide range of channel conditions.
