论文摘要
在LTE和5G无线通信系统中进行的研究使用了常见的现成硬件组件以及商业软件定义的无线电（SDR）硬件。最受欢迎的SDR平台之一是使用UHD驱动程序和运输协议框架的ETTUS USRP产品线。可以使用内核旁路框架与UHD一起提高系统性能。本文使用SRSLTE作为SDR应用程序在SDR环境中使用DPDK研究UHD。我们使用IPERF3网络性能应用程序提出了测量结果，该应用程序在使用内核旁路框架时显示了性能改进，以促进SDR应用程序和无线电硬件之间的网络接口通过网络接口进行数据传输。
Research conducted in LTE and 5G wireless communications systems uses common off-the-shelf hardware components and commercial software defined radio (SDR) hardware. One of the more popular SDR platforms is the Ettus USRP product line which uses the UHD driver and transport protocol framework. System performance can be increased using kernel bypass frameworks along with UHD. This paper investigates UHD with DPDK in an SDR environment using srslTE as the SDR application. We present measurement results using the iperf3 network performance application that show performance improvements when employing a kernel bypass framework to facilitate data transfer over the network interface between the SDR application and the radio hardware.
