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. Two specific applications that we are working on are the wireless transmission of sensor data from the brain to better understand its functions and the intelligent dynamic use of the radio spectrum (which is a finite natural resource) to accommodate general wireless communications from cell phones, computers, etc. 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 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 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 / Spring 2020
    Examines a special topic in Electrical, Computer and Energy Engineering. May be repeated for up to 9 total credit hours.
  • ECEN 5682 - Theory and Practice of Error Control Codes
    Primary Instructor - Spring 2020
    Introduces error control coding techniques for reliable transmission of digital data over noisy channels. Topics include algebraic characterizations of cyclic codes, convolutional codes, modern graph codes, decoding algorithms for block codes, Viterbi algorithm and iterative decoding on graphs. Applications include modern digital communication and storage systems including deep space communications, satellite broadcasting, cellular networks, and optical disk storage.
  • ECEN 6950 - Master's Thesis
    Primary Instructor - Spring 2020
