摘要:

用于无线通信网络的能量收集是允许终端从周围环境中的外部能量源对其电池再充电的新范例。一种有前途的能量收集技术是无线电力传输,其中终端从电磁辐射中收集能量。因此,可以从周围电磁源或从出于能量收集目的而有意地发射电磁能量的源机会性地收集能量。当源执行同时无线信息和功率传输(SWIPT)时,出现特别有趣和具有挑战性的场景,因为强信号不仅增加功率传输,而且还增加干扰。本文概述了SWIPT系统,特别侧重于整流天线电路的硬件实现和实用技术,实现SWIPT在时域,功率,天线和空间。本文还讨论了SWIPT技术在现代通信网络的资源分配和协作认知无线电网络的背景下的潜在整合的好处。

英文摘要:

Energy harvesting for wireless communication networks is a new paradigm that allows terminals to recharge their batteries from external energy sources in the surrounding environment. A promising energy harvesting technology is wireless power transfer where terminals harvest energy from electromagnetic radiation. Thereby, the energy may be harvested opportunistically from ambient electromagnetic sources or from sources that intentionally transmit electromagnetic energy for energy harvesting purposes. A particularly interesting and challenging scenario arises when sources perform simultaneous wireless information and power transfer (SWIPT), as strong signals not only increase power transfer but also interference. This paper provides an overview of SWIPT systems with a particular focus on the hardware realization of rectenna circuits and practical techniques that achieve SWIPT in the domains of time, power, antennas, and space. The paper also discusses the benefits of a potential integration of SWIPT technologies in modern communication networks in the context of resource allocation and cooperative cognitive radio networks.
