摘　　要：采用（２，１，３）卷积码，仿真和讨论了标准图像通过具有四种不同调制方式和两种不同车速的八个移动信道的神经网络译码器性能，并且研究了在移动信道中卷积码快衰落特征对图像传输可靠性的影响和纠错性能。得到一些重要的结论，并提出一些移动通信系统中图像传输的建议。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.
