Teaching

courses taught

  • CYBR 5200 - Introduction to Wireless Systems
    Primary Instructor - Fall 2020
    Overviews the distinctive characteristics of the wireless communications medium. Topics covered include: Analog signals, Antennas and Propagation, Digital Signals, Sampling, Quadrature Signals, Digital Modulation, SNR and SINR Concepts, Channel Models, Channel Statistics, and Link Budgets. The course includes an introduction to MIMO and beam-forming as implemented in modern communication systems. Software Defined Radio (SDR) is introduced to facilitate student hands-on learning of radio operation. Previously offered as a special topics course. Recommended prerequisites: CYBR 5010 and CYBR 5012. Same as CSCI 5200 and CSCI 4200.
  • CYBR 5830 - Special Topics
    Primary Instructor - Fall 2019
    Current topics in technology, cybersecurity and policy.
  • CYBR 6200 - Advanced Wireless Lab
    Primary Instructor - Spring 2020
    Provides a comprehensive, hands-on set of laboratory exercises for the teaching and demonstration of key technical skills required to understand, build, test, and analyze both analog and digital wireless communications concepts. In conjunction with lecture-based content to provide a solid foundation in digital communication theory, SDR-based laboratory exercises enable the synthesis of several fundamental concepts utilizing the latest, modern communications systems technologies. Recommended prerequisites: CYBR 5210 and CYBR 5220.
  • CYBR 6950 - Master's Thesis
    Primary Instructor - Fall 2021
    Original and independent research conducted by a graduate student under the supervision of a faculty advisor. Formerly TLEN 6950.
  • TLEN 5700 - Research Methods
    Primary Instructor - Fall 2018
    Develop basic concepts and methods for pursuing quantitative and qualitative research. Students will develop a research proposal that will be completed in TLEN 5710 or as a Master's Thesis. Writing skills test required.
