Research Projects

  • I6 light bulb

    Dynamic Spectrum Access Enabled "IOT" Radio

    The goal of this project is to develop a single board, battery powered software defined radio for Internet-of-Things.

    The motivation of this project is the development of a new radio that is supporting the research efforts for the emerging "Internet of Things" (IOT). IOT has not developed specific standards, but is expected to revolutionize the industry. Through this research project, we hope to use a cognitive RF front-end control to simplify radio design and implement a physical layer of 4G LTE as an example IOT radio.

  • National Science Foundation

    SDR-based High Resolution Cannel Sounder with Wireless Closed-Loop Control

    The goal is to build a SDR-based mobile channel sounder for characterizing new sepctrum sharing channels.

    Emerging spectrum sharing applications need a channel sounder that is low cost and light-weight, with enough time resolution. It is desirable to be software programmable in the back end with a single control point. We plan to develop a mm-wave version to address the need of 5G communications.

  • Army Research Office

    Cognitive Medical Wireless Test Bed System (COMWITS)

    The goal of the COMWITS project is to build an advanced medical wireless testbed that provides a unique opportunity for researchers to test innovative cognitive wireless communications, sensor networks, and biomedical applications under real world conditions.

    COMWITS enables medical DoD applications to ensure the integrity of new innovations to provide essential intelligence, surveillance, and reconnaissance capabilities. The testbed system can also being used by external researchers and industries through collaboration as well as undergraduate students through the NSF Research Experience for Undergraduates program.

    Ensuring Operational Privacy of Primary Users in GEO Location Database-Driven Sharing

    The goal of this project is to develop a threat model for spectrum utilization of primary users from the database and identify techniques to preserve privacy.

    The ability to protect the operational information of federal users is the major hurdle preventing the federal government from sharing spectrum bands. This project is to try and develop threat mitigation techniques and quantify their effectiveness in preserving operation privacy in database enabled spectrum sharing and systems operations.

    Robust Satellite Communications Under Hostile Interference

    The goal of this project is to identify complex forms of communications jamming, such as reactive jamming or protocol-aware jamming and come up with counter measures. The intent is to incorporate a cognitive component, using optimization and machine learning.

    This research will enable wireless communications under extremely harsh communication conditions, such as sophisticated adversarial jamming and augment existing anti-jam mechanisms such as adaptive nulling.

    Vulnerabilities of 4G LTE Cellular Systems to Radio Frequency Interference

    Vencore is sponsoring Wireless @ Virginia Tech to investigate vulnerabilities of 4G LTE cellular systems to radio frequency interference."

    Virginia Tech researchers also plan to identify approaches to mitigate the most likely types of interference to 4G LTE cellular systems
