Abstract:

The principles of encoding and decoding of Low-Density Parity-Check codes are presented, and the structure for Joint Source-Channel Coding in image transmission system is constituted on LDPC codes. The performance of the structure is analyzed and the future development of LDPC codes’ application on JSCC is also described.
