Abstract

In order to achieve effective and reliable video transmission, a video joint coding scheme based on dictionary learning and the concatenation of LT code and LDPC code is proposed for underwater single-photon com-munication system. Sparse coding based on dictionary learning greatly compresses the amount of video data. According to the deletion characteristic of underwater single-photon channel, using the LT-LDPC channel concatenated coding method can overcome the disadvantage of excessive decoding overhead of LT code. Aiming at the problem of decoding failure probability of LT coding, a double feedback mechanism for decoding success is proposed. The experimental results show that when the channel error rate is in the order of 10-2 and the video compression rate is 75.6%, the video frames can be reconstructed with an average peak signal-to-noise ratio (PSNR) of 37.4921 dB.

水下单光子视频通信联合编码研究

为了实现有效、可靠的视频传输，提出了一种基于字典学习和LT码与LDPC码拼接的水下单光子通信系统视频联合编码方案。基于字典学习的稀疏编码极大地压缩了视频数据量。根据水下单光子信道的删除特性，采用LT- ldpc信道级联编码方法可以克服LT码译码开销过大的缺点。针对LT编码的译码失败概率问题，提出了译码成功的双反馈机制。实验结果表明，当信道误码率为10-2，视频压缩率为75.6%时，重构的视频帧平均峰值信噪比(PSNR)为37.4921 dB。
