research overview

  • 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, and the detection of anomalies in the use of the radio spectrum. An emerging field of interest is the combination of signal processing, communications, and machine learning to produce adaptive and intelligent communication devices.

selected publications


courses taught

  • ECEN 2270 - Electronics Design Lab
    Primary Instructor - Spring 2020 / Fall 2020 / Spring 2021
    Provides an introduction to analysis, modeling, design, and testing of analog electronic circuits in a practical laboratory setting. The laboratory is centered around a robot platform and includes design, SPICE simulations, prototyping and testing of circuits necessary to drive and remotely control the robot.
  • ECEN 2350 - Digital Logic
    Primary Instructor - Fall 2018
    Covers the design and applications of digital logic circuits, including both combinational and sequential logic ciruits. Introduces hardware descriptive language, simulating and synthesis software, and programming of field programmable arrays (FPGAs).
  • ECEN 4242 - Communication Theory
    Primary Instructor - Fall 2018 / Fall 2019
    Covers modern digital and analog communication systems. Analysis and design of communication signals, transmitters, channels, and receivers. Amplitude and angle modulation and demodulation are treated as well as theory and application of digital data transmission. Emphasis is also placed on the analysis and mitigation of the effects of noise through signal design at the transmitter and signal processing at the receiver.
  • ECEN 4632 - Introduction to Digital Filtering
    Primary Instructor - Fall 2020
    Covers both the analysis and design of FIR and IIR digital filters. Discusses implementations in both software and hardware. Emphasizes use of the FFT as an analysis tool. Includes examples in speech processing, noise canceling, and communications.
  • ECEN 4652 - Communication Laboratory
    Primary Instructor - Spring 2019 / Spring 2020
    Analysis and design of realistic communication signals in a modern digital signal processing environment. Covers both analog and digital communication signals with and without noise and distortion. Pulse amplitude modulation is used initially at baseband and then combined with amplitude and phase/frequency modulation to produce the kind of bandpass signals that are used in cell phones and wireless data networks.
  • ECEN 5002 - Special Topics
    Primary Instructor - Spring 2019
    Examines a special topic in Electrical, Computer and Energy Engineering. May be repeated for up to 9 total credit hours.
  • ECEN 5017 - Special Topics
    Primary Instructor - Spring 2020
  • ECEN 5632 - Theory and Application of Digital Filtering
    Primary Instructor - Fall 2020
    Digital signal processing and its applications are of interest to a wide variety of scientists and engineers. The course covers such topics as characterization of linear discrete-time circuits by unit pulse response, transfer functions, and difference equations, use of z-transforms and Fourier analysis, discrete Fourier transform and fast algorithms (FFT), design of finite and infinite impulse response filters, frequency transformations, study of optimized filters for deterministic signals.
  • ECEN 6950 - Master's Thesis
    Primary Instructor - Fall 2020 / Spring 2021
