摘要
传统的分布式信源编码在城域量子通信中有高误码率和低压缩率的缺点,因此提出一种改进的分布式信源编码算法,在信源译码器的设计中,冗余技术用于纠错检错,基于边信息的和冗余相结合的低密度奇偶校验码设计分布式信源编码.实验表明:这种改进的分布式信源编码算法可以保持高压缩率,并在城域量子通信中系统的内部相关性强时更易于实现.
Abstract
Traditional distributed source coding(DSC)has the disadvantages of high error rate and low compres-sion rate in metropolitan quantum communication.Therefore,an improved distributed source coding algorithm is proposed in this paper.In the design of the source encoder,Redundancy technology is used for error correction and detection,and then the joint design of Low-Density Parity Check(LDPC)code with redundancy and side in-formation is adopted to conduct distributed source coding.Experiments show that the improved distributed source coding algorithm can keep a high compression rate and is easier to implement in metropolitan quantum communi-cation systems with strong internal correlations.
