| 摘 要： | 研究了一类依赖信道状态的高斯脏纸正交中继信道,其中,源节点到中继节点间的信道以及源节点和中继节点到目的节点间的信道相互正交,且分别受到服从高斯分布的加性干扰Sr和Sd的影响.假设Sr和Sd相互独立,且源节点和中继节点均非因果已知Sr和Sd,基于协作的脏纸编码（dirty-paper coding,DPC）和部分译码前传（partial-decode-and-forward,PDF）中继策略,得到了该信道容量的确切表达式.该信道容量的表达式与不受干扰的正交中继信道的容量表达式相同,此结果表明：即使目的节点未知加性干扰Sr和Sd,但通过协作的脏纸编码,可以完全消除加性干扰对信道容量的影响.

| Abstract: | A channel state dependent Gaussian dirty-paper orthogonal relay channel is studied,in which the channel from the source to the relay and that from the source and the relay to the destination are orthogonal to each other,they are corrupted by additive Gaussian interferences Sr and Sd,respectively.Assuming that Sr and Sd are independent and known to both the source and the noncausal relay,the formula of the channel capacity is obtained based on cooperative dirty-paper coding （DPC） and partial-decodeand-forward （PDF） relaying.It is the same as that of the state-independent orthogonal relay channel.The result shows that the additive interferences Sr and Sd can be completely cleaned by cooperative DPC,if they are unknown to the destination. |
