Communications Technology Laboratory /Spectrum Technology and Research Division

Applied Systems Metrology Group

Applied Systems Metrology Group

Develops and applies cutting-edge measurement techniques to characterize, analyze, and evaluate communication and remote sensing systems in a congested and dynamic spectrum environment.  Research in systems metrology, data analytics, and related machine learning methods to derive novel test capabilities for the characterization of complex and closed-box systems.  Identify future spectrum issues and lay the foundation for testing.

Major Activities:

  • Technical support for NASCTN projects
  • Testbed automation and sensor development 
  • Methodologies for communication systems testing and spectrum monitoring

Projects

Deep Generative Modeling for Communication Systems Testing and Data Sharing

Completed
After initial investigations with simulated datasets, we plan to develop generative models using real datasets. Potential applications of this work include generation of waveforms for interference testing, characterization of closed-box communication systems, and signal obfuscation for data sharing

CBRS Sharing Ecosystem Assessment

Ongoing
Background: In 2020, FCC auction 105 auctioned licenses in the Citizens Broadband Radio Service (CBRS). CBRS (3.55 GHz to 3.7 GHz) has a three-tiered framework to accommodate shared federal and non-federal use of the band. The DoD 3.5 GHz Transition Plans focus on ecosystem validations

Adaptive Closed-Box Interference Susceptibility Testing

Ongoing
Our approach combines state-of-the-art testbed automation, RF metrology, data analytics, and machine learning to develop flexible, broad-purpose methods that will enable efficient, rigorous testing. Specifically, we plan to establish methods for experimental characterization of closed-box
