Real-time Prototyping Platform for Advanced Massive MIMO Algorithms
Presenters: Douglas Kim, Nikhil Kundargi, Carsten Unger, National Instruments
This demonstration will feature the National Instruments MIMO prototyping platform that can be used to create real-time, over-the-air Massive MIMO testbeds. In addition to tightly synchronized RF channels, the FPGA source code supports a fully streaming, real-time, 20 MHz TDD uplink and downlink PHY layer reference design based upon the LTE standard. The number of antenna channels is reconfigurable through software to support anywhere from 4 to 128 antennas. FPGA-based MIMO precoding and decoding IP is also software reconfigurable and scales with the number of antennas. Over-the-air synchronization and calibration is also available with support for up to 12 single antenna mobile users. Channel estimation and reciprocity is implemented in the FPGA and provides compensation for all RF channels. A streaming video example is also provided out-of-the-box to demonstrate how an application can be run on top of the MAC and PHY layers. The FPGA source code is also fully open and modifiable so that it can be tailored to specific design requirements.
Real-time Prototyping of Advanced 5G Networks using National Instruments SDR Platform
Presenters: Vincent Kotzsch and Amal Ekbal, National Instruments
National Instrument’s (NI) software-defined radio (SDR) platform will be used a solution to conduct practical verification of proposed multi-node wireless networks that will include multiple 5G technologies. This demonstration shows an architectural concept for prototyping future 5G systems fulfilling several key performance indicators (KPI) such as high-throughput and low latency as well as the combination of sub-6GHz and millimeter wave systems. We show a rapid prototyping exercise that involves the full stack of the communication system from the upper layers to the new advanced PHY/MAC techniques under discussion in 5G network design. We will show how NI LabVIEW graphical system design software is able to address the challenges involved in full wireless communications stack prototyping by providing a common development environment for all the heterogeneous elements in the NI SDR system (i.e., the GPP, RTOS, FPGA, converters and RF components), with tight hardware/software integration and a good abstraction layer.
mmWave Communications Link for Prototyping
Presenters: Sarah Yost and Ahsan Aziz, National Instruments
This demonstration will show a hardware and software platform that can be used to prototype mmWave communications systems. The hardware will be running an over the air real-time 2x2 MIMO radio link operating at E-band that supports 2 GHz of bandwidth and achieves over 14.5 Gbps data throughput. It is the first-ever software-defined prototyping platform, which is open and fully modifiable for designing and testing a real-time bi-directional, over-the-air mmWave communication system. The system is fully programmed by LabVIEW. The RF front end of the transceiver supports a carrier frequency between 71-76 GHz with 2 GHz real-time bandwidth. The base-band processing unit consists of FPGA modules and Intel cores running a real time OS. This demonstration will provide an overview of the software architecture, real time signal processing algorithms and data exchange across modules. It shows how the modular software architecture and the signal processing design enable us to switch between SISO and different modes of MIMO system configuration.
Network Full-Duplex System: A Compact FD MIMO and 3D Ray-tracing based Emulator
Presenters: Jaeweon Kim, National Instruments
Min Soo Sim, Minkeun Chung, Dong Ku Kim, Chan-Byoung Chae, Yonsei University
In theory, full-duplex schemes should help double, or get closer to doubling, the network capacity by doubling the use of a given spectrum. Full duplex techniques have been successful in wired environments but the practicality in wireless scenario has been an open question. This demonstration presents advanced full-duplex radio technologies as a key technology for 5G wireless communications. A real-time MIMO full-duplex system prototype with a software-defined radio (SDR) platform of National Instruments (NI), to prove the practicality of our novel self-interference cancellation techniques is demonstrated. Also, this demonstration shows a real-time full-duplex system along with power amplifier characterization and a system-level evaluation of full-duplex cellular systems using Wireless System Engineering (WiSE)–a 3D ray-tracing tool developed by Bell Labs. The emulated throughputs of full-duplex systems via 3D ray tracing will be presented to show that full duplex improves a system throughput dramatically.
Real-time Uplink Multi-user MIMO Testbed with Carrier Frequency Offset Pre-Correction for Next-Generation Wi-Fi
Presenters: Hamed Pezeshki and Sahand Golnarian, University of Notre Dame
Rui Yang, Interdigital
Amal Ekbal, National Instruments
Nicholas Laneman, University of Notre Dame
This demonstration focuses on creating a testbed to study various design trade-offs in uplink multi-user MIMO (UL MU-MIMO) systems. Specifically, we validate protocols and algorithms to achieve timing and carrier frequency synchronization as well as spatial separation of uplink signals at the AP. Our testbed enables us to analyze the UL MU-MIMO throughput performance as a function of CFO estimation errors by comparing the TX and RX signal constellations and computing a bit-error-rate. Moreover, we will assess the performance of the downlink triggering algorithm for CFO estimation in situations in which packets from the two stations arrive at the AP synchronously or asynchronously. Finally, using the testbed, we demonstrate the effect of power control on the over-the-air performance of UL MU-MIMO.
Enabling Time-Sensitive Communication over Wi-Fi
Presenters: Dave Cavalcanti, Christopher Hall, Preston Hunt, Ganesh Venkatesan, Intel Corp.
Requirements for precise time coordination and reliable wireless communications between networked systems are emerging in several domains, from Industrial Internet, to Autonomous Vehicles, and 5G Telecom infrastructure. This demonstration will provide an insight on challenges related to precise time synchronization and collaboration in distributed computing systems. The demo will use an industrial control application scenario to show time synchronization capabilities defined in the 802.1AS standard and coordination between sensors and actuators over an 802.11 network. The demo will also include discussions on the limitations of the implemented technology and potential evolution to support more challenging applications.

Presenters: Changchun Xu, Yan Wang, Dong Li, Yuanyuan Wang, Huawei Technology Co., Ltd.
This demonstration showcases a dynamic LAN (called Mobile LAN) for LAN service at the edge of mobile network. The user can access Mobile LAN at any time and any location as required. A prototype of Mobile LAN is demonstrated with three use cases to show the features, including on-demand creation, automatic migration and adjustment, and dynamic loading of edge application.
Using MPTCP to Enhance the U-vMOS Performance
Presenters: Qing Xu and Pengcheng Tang, Huawei Technology Co., Ltd.
The U-vMOS is a user-centric video experience evaluation system developed by Huawei based on the original ITU-T vMOS. MPTCP (Multipath TCP) is a new TCP extension that allows spreading data across several paths. The aim of this demonstration is to use MPTCP to enhance the U-vMOS performance of the network, and enhance the video experience of users. In order to efficiently use the resources of multiple network paths, this demonstration implements optimized MPTCP algorithms, such as scheduling and buffer sharing.
In-band Full-Duplex Mobile Radio for Simultaneous Transmission and Reception
Presenters: Byung-Jae Kwak, QUI Inc.
Youngsik Kim, Handong Global University
In-band full-duplex (IFD) has been attracting a lot of attention as one of the key technologies for 5G wireless communications, because theoretically it can improve frequency efficiency of wireless communications systems by a factor of 2. In this demonstration, IFD enabled FRS (family radio service) mobile radios will be used. Each radio device will be completely standalone with no measuring instrument, signal generator, or power supply attached. The demonstration will not require any setup in advance, and the audience are welcome to participate in the demonstration by trying out the IFD enabled mobile radios.
