Integrated code design for a joint source and channel LDPC coding scheme
Hsien-Ping Lin, Shu Lin, Khaled Abdel-Ghaffar · 2017
This paper presents a design of LDPC codes for a joint source-channel (JSC) coding system. In the construction of such an LDPC code, the source compression matrix and the channel code parity-check matrix are designed jointly. The integrated matrix is used for both JSC encoding and decoding. Experimental results show that the codes constructed not only perform well in the waterfall region but also achieve low error-floors.
