中文摘要:
      设计了一种基于软件无线电、节点相对独立、分布式波束形成的微波能量无线传输方法。采用扩展 卡尔曼滤波算法估计和校正每个发射节点发射信号的载波频率偏移,并采用一比特反馈算法调整每个发射节点的 发射相位,以此将它们的能量集中在接收节点,使收集能量最大化从而提高输能效率。实验结果表明:采用所设计 的方法在四个发送节点的情况下,接收节点可以获得11. 54 dB 的增益,可以大幅提高微波输能效率,为进一步展开 微波能量为低功耗电子设备无线充电奠定基础。
英文摘要:
      The paper proposes a wireless transmission method of microwave energy based on software radio with completely independent nodes and distributed beam forming. The extended Kalman filter algorithm is used to estimate and correct the carrier frequency offset of each transmitting node, and the one-bit feedback algorithm is used to adjust the transmitting phase of each transmitting node, so as to concentrate their energy on the receiving node, maximize the collected energy and improve the energy transmission efficiency. The experimental results show that under the condition of four sending nodes, the receiving node can obtain 11. 54 dB gain, which can greatly improve the microwave energy transmission efficiency, laying a foundation for further expanding the microwave energy and wireless charging of low-power electronic devices.
