NSF SWIFT: Passive Active Spectrum Sharing (CU-PASS)
Project Description:

Project Goals:

Ìý
The objectives of the long-term RF baseline noise are:
Analysis and characterization of RF noise with respect to environmental parameters to identify patterns. The team will also explore RF noise mitigation approaches based on the results.
Exploration of new approaches to dynamic spectrum sharing between passive and active services.
Quantitative analysis of dynamic spectrum sharing mechanisms extended to enable sharing between passive and active services.
Exploration of approaches to optimize the efficiency and security of dynamic spectrum sharing.
​
​ExplorationÌýof operational mechanisms for a National Radio Dynamic Zone (NRDZ). PASS will make multiple contributions to the scientific community, including:
Tested, documented, and publicly accessible best practices for RF noise measurement.
Documented data and metadata formats for RF noise measurements, and open RF noise data sets to enable multi-institutional collaboration in measurement and analysis.
Tools and metrics for quantitative analysis of dynamic spectrum sharing effectiveness.
Processes for optimizing the effectiveness and security of dynamic spectrum sharing.
Preliminary operational definition and requirements for a NRDZ.
​
The PASS project will have a broad impact beyond contributions to research and engineering. The same results, along with the exploration of security approaches will inform the commercial world as it develops and deploys systems that exploit spectrum sharing to gain spectrum access. Documents and workshops that result from the PASS project will inform the curricula of institutions training the next generation of RF engineers and scientists. The RF noise measurements and analysis, quantitative evaluation of spectrum sharing mechanisms, and NRDZ requirements will inform spectrum policy makers.
