Distributed Source Coding Based on Side Information and LDPC
Considering the shortcomings of distributed source coding(DSC)in metropolitan area quantum communication,such the bit error rate is high and the compression ratio is low,an improved distributed source coding is proposed in this paper.In the design of the source encoder,redundancy technology is used to provide error protection,and then the joint design of Low-Density Parity Check code(LDPC)with redundancy and side information is adopted to conduct distributed source coding.Experimental results show that the proposed method can keep a high compression rate and be easily implemented when a strong internal correlation of the quantum communication sources in metropolitan areas.
