中文摘要: 本项目拟针对中继信道模型,基于联合信源-信道编码,研究逼近中继信道容量限的压缩-转发中继协作传输理论及设计方法。首先,利用信息理论工具,研究基于联合信源-信道编码压缩-转发中继传输策略的中继信道容量限。然后,在此信息理论研究基础上,系统研究基于联合信源-LDPC卷积编码的压缩-转发中继协作传输方案设计,包括中继节点压缩策略的设计,联合信源-LDPC卷积编码方案的设计以及目的节点的联合译码算法设计等。最后,对联合信源-LDPC卷积码,以及压缩-转发传输方案进行优化设计,以求逼近中继信道的容量限。希望通过本项目的研究,完善中继信道的信息理论体系,给出实际可行的基于联合信源-LDPC卷积编码的压缩-转发中继协作传输通信理论与设计方法,为未来宽带无线通信系统的设计和应用提供重要的理论依据和技术支持。

英文摘要: In this research project,the transmission theory and designing method of compress-and-forward (CF) relaying based on joint source-channel coding (JSCC) for approaching the capacity of the relay channel are studied.Fisrt, the capacity bound of JSCC-based CF strategy for the relay channel is studied. Second,on the basis of the above theoretical research, the study of CF scheme based on joint source-LDPC convolutional coding is made,including the design of compression strategies of the relay, the design of joint source-LDPC convolutional coding scheme, and the joint decoding algorithms of the destination.Finally, the optimal design of joint source-LDPC convolutional codes and the CF scheme for approaching the capacity of the relay channel is given.Through this research project, we want to perfect the information theory system of relay networks, and provide the transmission theory and designing method of CF relaying based on joint source-LDPC convolutional coding. These results will play a very important role in the design and application of the future wireless communication systems.
