Performance analysis and optimisation for edge connection of JSCC system based on double protograph LDPC codes

For a joint source–channel coding system based on double protograph low-density parity-check codes, the exchange of extrinsic information through edge connection between the source code and channel code is essential for good performance. In this study, the relationship between the performance and ed...
