无线电能传输中能量与信息的优化研究

Optimization Study of Power and Information in Wirelesss Power Transfer System

目前已有的研究无线电能与信息同时传输系统的文献大多只关注实现的具体方法,对于无线电能传输系统中信息与能量的关系,以及两者之间的优化方案还研究得不够深入。通过无线电能与信息传输系统中信道容量和传输效率的表达式,得到了当输入功率和输出功率受限时,信道容量的优化方案。在此基础上,进一步提出了当信道容量受限时传输效率的优化问题以及当传输效率受限时信道容量的优化问题。

Available documentation on systems of wireless power transmission and information transmission is mostly concerned about specific method of realization, and does not study in depth the relationship between information and energy in the wireless power transmission system or the optimization scheme between the two. The expression of channel capacity and transmission efficiency of the wireless power and information transmission system is used to obtain an optimization scheme of channel capacity in the case of limited input and output powers. On that base, it further studies optimization of transmission efficiency in the case of limited channel capacity, as well as optimization of channel capacity in the case of limited transmission efficiency.
