本文介绍了电磁调制信号射频 (RF) 平台的开发，该平台利用软件定义无线电 (SDR) 从新型磁电 (ME) 天线接收信息，该天线能够感测超低强度的低频磁场。该平台被用作研究和开发的一部分，利用微型 ME 天线和集成电路通过无线植入设备进行神经记录。为了对来自传感器的电磁调制信号的接收进行原型设计，利用多功能通用软件无线电外设 (USRP) 和 GNU 无线电工具包来实现不同操作条件下的实时信号处理。此外，还演示了 ME 天线如何捕获从 SDR 传输的射频信号以进行无线能量收集。
This article describes the development of a radio frequency (RF) platform for electromagnetically modulated signals that makes use of a software-defined radio (SDR) to receive information from a novel magnetoelectric (ME) antenna capable of sensing low-frequency magnetic fields with ultra-low magnitudes. The platform is employed as part of research and development to utilize miniaturized ME antennas and integrated circuits for neural recording with wireless implantable devices. To prototype the reception of electromagnetically modulated signals from a sensor, a versatile Universal Software Radio Peripheral (USRP) and the GNU Radio toolkit are utilized to enable real-time signal processing under varying operating conditions. Furthermore, it is demonstrated how a radio frequency signal transmitted from the SDR can be captured by the ME antenna for wireless energy harvesting.
