多天线中继干扰信道传输模型的容量与能量效率研究

"Interference channel with multiple-antenna relay model" is one of the key transmission models for future wireless communication systems. We will study the MIMO interference channel with multiple-antenna relay model following two parallel threads: (i) capacity and (ii) energy efficiency. Based on the concept of channel capacity, we will research the transmission scheme, the degrees of freedom, and the diversity multiplexing tradeoff and analyze the effects of the parameters in the transmission model. Moreover, we will derive the capacity of the transmission model for some special cases. Research on energy efficiency is a new trend in the field of network information theory and in this project, we will establish a concept model for energy efficiency, designed to fit the research related to the transmission model. We will further establish a research framework based on this energy efficiency concept to research the transmission model. With this research framework, we will study the energy efficiency in the MIMO interference channel with multiple-antenna relay model and research the optimal energy efficient transmission scheme in this transmission model. In this project we will also investigate the appropriate mathematical method to explore the relationship between the energy efficiency concept model, degrees of freedom and diversity gain. With this effort, we will be able to gain access to the results in the previous works, so as to enlarge the scope of this new framework.
