| 摘 要： | 提出了适合于卷积码的一种新的交错方案 .并在实现了卷积码的编码、Viterbi译码的基础上 ,对采取这种交错方案的 (2 ,1 ,3 )卷积码在移动图像通信系统中的抗干扰性能进行了计算机模拟 ,且与相同编码效率、相同交错时延的BCH(3 1 ,1 6,3 )码的结果做了比较 .计算机模拟结果表明 :采取合适交错方案的交错卷积码可明显改善图像质量 ,比交错BCH码更适合于移动衰落环境中图像的传输 ,是值得推荐的纠错抗干扰方案 .

| Abstract: | A novel interleaving scheme suitable to convolution al code is given.Based on convolutional coding and Viterbi decoding,the anti inte rfence performance of (2,1,3) convolutional code using this scheme in mobile ima ge communication system is simulated and compared with the performance of BCH(31 ,16,3) code which has the same coding rate and the same time delay of interleav ing with (2,1,3) convolutional code.The simulation results show that interleaved codes with suitable interleaving scheme can improve image quality obviously and are more suitable to image transmission than interleaved BCH codes in mobile fa ding channels.It should be suggested as an excellent error control scheme used i n mobile image communication systems. |
