英文摘要： This project focuses on study of the green wireless communications and explores the theoretical meaning of green communications from the perspective of transmission technologies. In order to reduce the energy consumption of wireless communication systems for the pressing energy crisis of the world, this project firstly focuses on the energy efficiency evaluation of green wireless transmissions and studies a new multi-dimensional energy efficiency criteria based on overall balancing spectrum efficiency, energy efficiency and quality of communication, as the theoretical guidance to design the optimal green wireless communication technologies. Under the new multi-dimensional energy efficiency criteria, the project will deeply study MIMO transmission technologies and provide energy-efficient transmission schemes in the more complex environment of multiuser MIMO scenarios, including power control, beamformong, pre-coding, etc. For OFDMA networks, the joint optimal resource configuration methods will be studied to improve energy efficiency and spectral efficiency. Furthermore, this project will analyze and design the cross-layer optimization schemes to meet the goal of entire system energy efficiency to reduce the energy of the usable bits. In conclusion, this project will contribute not only to the theoretical explor
