Abstract

While millimeter-wave (mmWave) wireless has recently gained tremendous attention with the transition to 5G, developing a broadly accessible experimental infrastructure will allow the research community to make significant progress in this area. Hence, in this paper, we present the design and implementation of various programmable and open-access 28/60 GHz software-defined radios (SDRs), deployed in the PAWR COSMOS advanced wireless testbed. These programmable mmWave radios are based on the IBM 28 GHz 64-element dual-polarized phased array antenna module (PAAM) subsystem board and the Sivers IMA 60 GHz WiGig transceiver. These front ends are integrated with USRP SDRs or Xilinx RF-SoC boards, which provide baseband signal processing capabilities. Moreover, we present measurements of the TX/RX beamforming performance and example experiments (e.g., real-time channel sounding and RFNoC-based 802.11ad preamble detection), using the mmWave radios. Finally, we discuss ongoing enhancement and development efforts focusing on these radios.
PAWR COSMOS试验台中的可编程和开放接入毫米波无线电
虽然毫米波(mmWave)无线最近随着向5G的过渡而获得了极大的关注,但开发一个广泛可访问的实验基础设施将使研究界在这一领域取得重大进展。因此,在本文中,我们提出了各种可编程和开放接入的28/60 GHz软件定义无线电(sdr)的设计和实现,部署在PAWR COSMOS先进无线试验台中。这些可编程毫米波无线电基于IBM 28 GHz 64元双极化相控阵天线模块(PAAM)子系统板和Sivers IMA 60 GHz WiGig收发器。这些前端与USRP sdr或Xilinx RF-SoC板集成,提供基带信号处理能力。此外,我们还介绍了使用毫米波无线电的TX/RX波束形成性能的测量和示例实验(例如,实时信道探测和基于rfnoc的802.11ad前导检测)。最后,我们讨论了针对这些无线电正在进行的增强和开发工作。
