采用 (2 ,1 ,3 )卷积码结合一种新的交织方案 :位交织方案作为抗干扰措施 ,模拟并讨论了标准灰度图像的数据在相同调制方式、不同车速的移动衰落信道中的抗干扰问题 ,且与周期交织方案的结果做了比较 .模拟结果表明 :卷积码更适合于快车速环境中图像数据的传输 .周期交织方案不适合于卷积码 ,而采用位交织方案的 (2 ,1 ,3 )卷积码可明显改善图像质量 ,大大提高了快衰落移动信道环境中图像通信系统的可靠性 . (2, 1, 3) convolutional code combined with a new interleaving scheme: bit interleaving scheme as an anti-interference measure to simulate and discuss the standard gray-scale image data in the same modulation, mobile speed fading channel The results show that the convolutional codes are more suitable for the transmission of image data in fast speed environment.The periodic interleaving scheme is not suitable for convolutional codes and the bit interleaving scheme (2, 1, 3) convolutional code can significantly improve the image quality, greatly improving the reliability of the image communication system in fast fading mobile channel environment.
