The Problem: Incumbent systems designed with expectation of quiet exclusive bands, guard bands, lower Tx power from nearby systems
-
Infrastructure that can’t move in frequency (science observations) or prohibitively expensive to move
-
Dynamic sharing won’t work
-
-
Jamming intentionally or unintentionally
-
Frequency tuning needed with tight filtering
-
The Solutions:
-
Spectral use database and RFI limits of necessary systems
-
RFI Mitigation and Secure-by-Design Communications
-
Algorithmic RFI mitigation
-
Infrastructure or science can’t move in frequency
-
-
-
Hardware RFI mitigation
-
Pair reconfigurable front-ends with software defined radios and radars
-
-
Create new frequency-agile sensing and communication systems that are secure by design
Expected High-Impact Outcomes
-
A Secure-by-design, Fully Reconfigurable Radio
-
True reconfigurability for communications and sensing systems breaking disciplinary barriers to combine hardware and software reconfigurability
-
Work with Thrust 2 to find optimal dynamic spectrum sharing techniques
-
Work with Thrust 1 to transition reconfigurability to >100 GHz technology
-
-
RFI Threat Modeling and Mitigation Toolset
-
Use VLBA archives and calibration data to develop an understanding of RFI
-
Work with Thrust 2 to develop tools for optimal scheduling of science projects, accounting for scientific and comms constraints
-
Improved algorithmic RFI mitigation processes
-
Enable open-world class discovery, where new types of waveforms and incumbent patterns are learned without supervised training.
