摘要
介绍了LDPC码的编译码原理,建立了一种应用LDPC码的联合信源信道编码图像传输系统结构,对其性能进行了分析,并给出了LDPC码在联合信源信道编码中应用的进一步研究方向.
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.
