| Abstract: | In this paper, we adopt the (2, 1, 3) convolutional code. We simulate and dis- cuss the performance of neural decoder of a standard image transmitted through totally eight mobile channels with four different modulation styles and two different vehicle speeds. We study the in- fluence of the fast - fading character to the reliability of image transmission and the error- correcting performance of the convolutional codes in mobile channel. we obtain some significant conclusions and propose some ideas for the image transmission in mobile communication system. |
