中文摘要： 为了应对能源危机和环境污染问题，发展绿色通信技术是当前通信界的一个重要课题。除了降低通信能耗，对新能源的有效利用也是实现绿色通信的重要一环。作为一种潜在的绿色能源，无线电波可以用来同时传输信息与能量。因此，有必要研究信息与能量同时传输的无线通信系统（简称为无线信能同传系统）及其高能效传输理论。本课题将利用信息论与凸优化等理论工具，针对多用户信能同传系统，开展系统能效的理论分析及高能效传输理论研究，具体包括：1）系统能效的成因关系及理论极限；2）高能效的接入机制与传输策略；3）非理想信道情况下的高能效鲁棒传输策略。本课题将在多用户信能同传系统高能效传输理论方面取得一些突破，使多用户信能同传系统的能量效率得到大幅度提高。

英文摘要： Green radio has been an important research topic under the pressure of energy crisis and environmental pollution. Besides energy saving, efficient utilization of new energy sources is also an important way to realize green radio. As a potential green energy source, radio signal can be used to simultaneously transmit information and power. Therefore, it is of great importance to investigate the communication system with the capability of simultaneous wireless information and power transfer (named SWIPT system) and its energy-efficient transmission technology. In this project, by using some advanced theoretical tools like information theory and convex optimization, etc, we will perform analysis on the energy efficiency of the multi-user SWIPT system, and study its energy-efficient transmission theory. Specifically, we will study 1) the impact factors and the theoretical limit of the system energy efficiency; 2) energy-efficient channel access mechanism and transmission strategy; 3) robust and energy-efficient transmission strategy under imperfect channel state information. This project aims to provide transmission theory for the multi-user SWIPT system and greatly increase its energy efficiency.
