英文摘要	Conference Name:11th IEEE International Conference on Trust, Security and Privacy in Computing and Communications, TrustCom-2012. Conference Address: Liverpool, United kingdom. Time:June 25, 2012 - June 27, 2012.; University of Bradford; IEEE Technical Committee on Scalable Computing (TCSC); IEEE; IEEE Computer Society; As the demand for e-Health care increases quickly, the transmission of medical images has been a crucial problem which needs to be solved as soon as possible. In the last decade, joint source-channel coding (JSCC), which combines the source coding with the channel coding reasonably to build an integral system so as to obtain significant improvement of system performance has attracted much attention. A framework of transmitting medical images by a P-JSCC scheme constructed from protograph low-density parity-check (P-LDPC) codes is proposed in this paper. Without loss of generality, we exploit a typical radiography image for simulation, and experimental results show that the receiver can recover the transmitted radiography image with good quality even at a very low signal-to-noise ratio (SNR); the P-JSCC scheme outperforms irregular-JSCC and regular-JSCC. 漏 2012 IEEE.
