This National Science Foundation project grant of $285,990 will fund research at Colorado State University from October 2022 through September 2025 under the Engineering program (CFDA 47.041). The university will develop a new mathematical framework for optimizing resilient spectrum coexistence between communication and radar systems using stochastic programming techniques. As demand for wireless connectivity and sensing capabilities increases, traditional deterministic constraints on spectrum...
This Project Grant award from the National Science Foundation (NSF) Directorate for Mathematical and Physical Sciences (CFDA 47.049 - Mathematical and Physical Sciences) supports research to quantify and mitigate interference from terrestrial cellular systems to satellite communications. The $728,637 award, granted on April 15, 2025, will fund extensive field measurements and the development of interference simulation models and machine learning-based mitigation techniques. The goal is to enable greater use of midband spectrum for cellular systems without significantly disrupting critical satellite communications. The project, titled "NEWSPECTRUM: Interference from Terrestrial Cellular Systems to Satellites: Measurement, Modeling, and Effective Mitigation Strategies," will be performed by the University of Southern California. No sub-awards are planned under this grant.
