3GPP 38系列标准（5G）中定义的一组物理层功能已在商业现货SDR产品中实现。该系统创建了一个工作在3.5GHz的空中链路，具有40MHz的信道宽度和使用256QAM。PHY层在SDR收发器的FPGA中执行;更高层在控制无线电前端的主机PC中执行。该链路以4K视频流作为有效载荷，允许我们进行以下实验：5G NR数字方案;用于减少OOB排放和提高频谱利用率的频率整形技术;高阶QAM调制;以及混合数字方案通信。
A set of physical layer features defined in the 3GPP 38 series standards (5G) were implemented in commercial off the shelf SDR products. The system created an over-the-air link operating at 3.5GHz, having 40MHz channel width and using 256QAM. The PHY layer was executed in the FPGA of the SDR transceiver; higher layers executed in the host PC controlling the radio frontend. With a 4 K video stream as payload, the link allowed us to experiment with: 5G NR numerologies; frequency shaping techniques for reducing OOB emissions and improving spectral utilization; higher order QAM modulation; and mixed numerology communications.
