m cube a millimeter wave massive mimo Software Radio
GetMobile: Mobile Computing and Communications, 2021Co-Authors: Renjie Zhao, Timothy Woodford, Teng Wei, Kun Qian, Xinyu ZhangAbstract:Millimeter-wave (mmWave) technologies represent a cornerstone for emerging wireless network infrastructure, and for RF sensing systems in security, health, and automotive domains. However, the lack of an experimental platform has been impeding research in this field. In this article, we propose to fill the gap with M3 (M-Cube), the first mmWave massive MIMO Software Radio. M3 features a fully reconfigurable array of phased arrays, with up to 8 RF chains and 256 antenna elements. Despite the orders of magnitude larger antenna arrays, its cost is orders of magnitude lower, even when compared with state-of-the-art single RF chain mmWave Software Radios. Case studies have demonstrated the usefulness of M3 design for research in mmWave massive MIMO communication and sensing.

ACM IEEE International Conference on Mobile Computing and Networking, 2020Co-Authors: Renjie Zhao, Timothy Woodford, Teng Wei, Kun Qian, Xinyu ZhangAbstract:Millimeter-wave (mmWave) technologies represent a cornerstone for emerging wireless network infrastructure, and for RF sensing systems in security, health, and automotive domains. Through a MIMO array of phased arrays with hundreds of antenna elements, mmWave can boost wireless bit-rates to 100+ Gbps, and potentially achieve near-vision sensing resolution. However, the lack of an experimental platform has been impeding research in this field. This paper fills the gap with M3 (M-Cube), the first mmWave massive MIMO Software Radio. M3 features a fully reconfigurable array of phased arrays, with up to 8 RF chains and 288 antenna elements. Despite the orders of magnitude larger antenna arrays, its cost is orders of magnitude lower, even when compared with state-of-the-art single RF chain mmWave Software Radios. The key design principle behind M3 is to hijack a low-cost commodity 802.11ad Radio, separate the control path and data path inside, regenerate the phased array control signals, and recreate the data signals using a programmable baseband. Extensive experiments have demonstrated the effectiveness of the M3 design, and its usefulness for research in mmWave massive MIMO communication and sensing.

Sora: High-Performance Software Radio Using General-Purpose Multi-Core Processors
Communications of the ACM, 2011Co-Authors: Kun Tan, Ji Fang, Yongguang Zhang, Jiansong Zhang, He Liu, Geoffrey M. VoelkerAbstract:This paper presents Sora, a fully programmable Software Radio platform on commodity PC architectures. Sora combines the performance and fidelity of hardware Software-defined Radio (SDR) platforms with the programmability and flexibility of general-purpose processor (GPP) SDR platforms. Sora uses both hardware and Software techniques to address the challenges of using PC architectures for high-speed SDR. The Sora hardware components consist of a Radio front-end for reception and transmission, and a Radio control board for high-throughput, low-latency data transfer between Radio and host memories. Sora makes extensive use of features of contemporary processor architectures to accelerate wireless protocol processing and satisfy protocol timing requirements, including using dedicated CPU cores, large low-latency caches to store lookup tables, and SIMD processor extensions for highly efficient physical layer processing on GPPs. Using the Sora platform, we have developed a few demonstration wireless systems, including SoftWiFi, an 802.11a/b/g implementation that seamlessly interoperates with commercial 802.11 NICs at all modulation rates, and SoftLTE, a 3GPP LTE uplink PHY implementation that supports up to 43.8Mbps data rate.

experimenting Software Radio with the sora platform
ACM Special Interest Group on Data Communication, 2010Co-Authors: Jiansong Zhang, Ji Fang, Kun Tan, Sen Xiang, Qiufeng Yin, Qi Luo, Yongguang ZhangAbstract:Sora is a fully programmable, high performance Software Radio platform based on commodity general-purpose PC. In this demonstration, we illustrate the main features of the Sora platform that provide researchers flexible and powerful means to conduct wireless experiments at different levels with various goals. Specifically, the demonstrator will show four useful applications for wireless research that are built based on the Sora platform: 1) A capture tool that allows one to take a snapshot on a wireless channel; 2) a signal generation tool that allows one to transmit arbitrary baseband wave-form over the air, from a monophonic tone to a complex modulated frame; 3) an on-line real-time receiving application that uses the Sora User-Mode Extension; and 4) a fully featured Software Radio WiFi driver (SoftWiFi) that can seamlessly inter-operate with commercial WiFi cards.
