同时无线信息和功率传输（SWIPT）是一种很有前途的解决方案，可以增加无线节点的寿命，从而缓解能量受限的无线网络的能量瓶颈。作为传统能量收集技术的替代方案，SWIPT依赖于射频信号的使用，预计将为无线通信网络的设计带来一些根本性的变化。本文重点介绍了先进的智能天线技术在SWIPT中的应用，包括多输入多输出技术和中继技术。这些智能天线技术有可能显着提高SWIPT的能源效率和频谱效率。不同的网络拓扑结构与单用户和多用户的研究，沿着一些有前途的解决方案，以实现系统性能和复杂性之间的有利权衡。还提供了一个详细的讨论未来的研究挑战的SWIPT系统的设计。
Simultaneous wireless information and power transfer (SWIPT) is a promising solution to increase the lifetime of wireless nodes and hence alleviate the energy bottleneck of energy constrained wireless networks. As an alternative to conventional energy harvesting techniques, SWIPT relies on the use of radio frequency signals, and is expected to bring some fundamental changes to the design of wireless communication networks. This article focuses on the application of advanced smart antenna technologies to SWIPT, including multiple-input multiple-output and relaying techniques. These smart antenna technologies have the potential to significantly improve the energy efficiency and also the spectral efficiency of SWIPT. Different network topologies with single and multiple users are investigated, along with some promising solutions to achieve a favorable trade-off between system performance and complexity. A detailed discussion of future research challenges for the design of SWIPT systems is also provided.
