远场无线电力传输（WPT）已成为物联网（IoT）和无线传感器网络（WSN）的潜在电源。电力传输范围的扩大是使该技术可行的关键挑战之一。在本文中，我们实验研究了一种信道自适应联合波束形成和波形结构，以扩大功率传输范围。WPT实验已经在真实的室内环境中，在不同距离的各种无线信道中进行。用简单的分析模型拟合了测量数据，分析了输出直流功率和可实现的范围改进，这取决于信号设计方案、音调和天线的数量。该模型显示了信号设计与输出直流功率和可实现范围之间的明确关系，并突出了所提出的架构在扩大功率传输范围方面的显着优势。
Far-field Wireless Power Transfer (WPT) has emerged as a potential power source for the Internet of Things (IoT) and Wireless Sensor Network (WSN). The expansion of the power transfer range is one of the key challenges to make the technology viable. In this letter, we experimentally study a channel-adaptive joint beamforming and waveform architecture to expand the power transfer range. WPT experiments have been conducted in a variety of wireless channels at various distances in a realistic indoor environment. The measurement data have been fitted using a simple analytical model to analyze the output DC power and achievable range improvement depending on the signal design schemes and the number of tones and antennas. The model shows a clear relationship between signal design versus output DC power and achievable range, and highlight the significant benefit of the proposed architecture to expand the power transfer range.
