Peter Mathys’ research focuses on modern electronic communication systems and their applications. Software defined radios are the key to implementing such systems for teaching, research, and practical applications. Specific applications that we are working on are the intelligent dynamic use of the radio spectrum (which is a finite natural resource) to accommodate general wireless communications from cell phones, computers, etc, the measurement and prediction of radio wave propagation, the detection of anomalies in the use of the radio spectrum, and the safety and security of vehicle-to-everything (V2X) communication. An emerging field of interest is the combination of signal processing, communications, and machine learning to produce adaptive and intelligent communication devices.
