Pi-Radio v1软件定义无线电（SDR）平台集成了一个工作在57-64 GHz频段的4通道全数字收发器板，并连接到功能强大的Xilinx基于RFSoC的ZCU 111评估板。本文介绍了各种校准程序，以避免依赖昂贵的实验室设备和基础设施，如频谱分析仪，信号发生器，甚至消声室。最后，我们通过几何确定的波束赋形权重启用波束赋形演示本文，从而证明SDR节点已被正确校准。
The Pi-Radio v1 software-defined radio (SDR) platform incorporates a 4-channel fully-digital transceiver board that operates in the 57–64 GHz band and connects to the powerful Xilinx RFSoC-based ZCU111 evaluation board. This paper illustrates various calibration procedures that have been implemented to avoid relying on expensive laboratory equipment and infrastructure like spectrum analyzers, signal generators, or even anechoic chambers. We conclude this paper with a demonstration of beamforming enabled through geometrically determined beamforming weights, thereby demonstrating that the SDR nodes have been calibrated correctly.
