摘　　要：在图像通信中,为了节约网络资源同时保证在多跳网络中的可靠传输,该文提出了一种基于编码统计的滑窗BATS码和小波SPIHT编码的图像传输方案。该方案同基于传统BATS码和SPIHT编码的图像传输方案、基于普通滑窗BATS码和SPIHT编码的图像传输方案相比,不仅较好地改善了BATS码的编码随机性对传输可靠性的影响,还在保证方案具备渐进传输特性的同时显著地降低了传输时延,从而提高了图像通信的用户体验质量(QoE)。In image communication,in order to save network resources and ensure reliable transmission in multi hop network,an image transmission scheme based on sliding window batched sparse(BATS)code and wavelet set partitioning in hierarchical trees(SPIHT)coding is proposed.Compared with the image transmission scheme based on traditional BATS code and SPIHT code,and image transmission scheme based on common sliding window BATS code and SPIHT code,this scheme can not only improve the influence of coding randomness of BATS code on transmission reliability,but also greatly reduce the transmission delay while ensuring the progressive transmission characteristics of the scheme,so as to improve the quality of experience(QoE)on the image communication system.
