中文摘要： 在无线通信网络中引入中继技术，可取得提高频谱效率、增大覆盖面和节省无线资源等诸多优势。然而，由于受到半双工通信模式的限制，单向中继系统的频谱效率受到严重影响。双向中继通信可以有效地提高单向无线通信系统的频谱效率，已获得越来越多的关注。相比于已相对成熟的单向中继通信系统，双向中继通信网络的自适应传输方案现有的研究成果仍然较少。本课题将围绕设计和分析双向中继通信系统中高频谱效率的自适应传输技术而展开研究：（1）自适应调制技术在双向中继通信中的应用；（2）基于信源、中继选择的自适应传输技术设计与分析；（3）利用MIMO系统天线技选择术，设计和分析双向中继通信的自适应传输方案；（4）推导不同自适应传输场景下双向中继系统的容量限。

英文摘要： Wireless relaying technology has been widely adopted in wireless systems since it has the potential of improving system spectral efficiency, extending wireless service coverage and saving wireless resources. However, due to the half-duplex constraint, the spectral efficiency of one-way relay systems is hardly to be increased further. Two-way relaying has received a lot of attention because of its ability to significantly enhance the system spectral efficiency. Compared with one-way relaying, little research work has been done been done for the adaptive transmission schemes in two-way relay systems. The proposed research is to design and analyze new spectrum-efficient adaptive transmission schemes in two-way relay systems, which includes: 1) Application of adaptive modulation schemes in two-way relay systems 2)Design and analysis of novel adaptive transmission schemes based on source and relay selection 3)Design and analysis of novel adaptive transmission schemes combined with MIMO antenna selection 4)Derivation of the capacity of two-way relay systems under various adaptive transmission scenarios.
