Overview

Explore Radio Frequency Spectrum Sharing and Spectrum Superiority related concepts through interactive experiments and programming mini-projects.

These self-paced online courses introduce fundamental concepts and recent developments related to efficient, effective use of the radio frequency (RF) spectrum in constrained, congested, and contested (complex) RF environments.  Participants explore concepts in depth through interactive simulations to apply and extend knowledge gained through lectures and diverse supplemental learning resources.

In the final course, participants apply rule-based artificial intelligence as well as machine learning approaches in challenging, non-graded mini-projects.  In the mini-projects you will modify provided, user-editable transmission parameter adaptation code for use in simulated RF environments.  Mini-project goals include maintaining wireless link quality in fading channels and avoiding an interfering and/or higher-priority signal in a shared RF band.

Included courses (2.0 CEUs Total):

HLSI-01 (0.5 CEUs):  Fundamental Concepts for Wireless Communications (FCW)
HLSI-02 (0.5 CEUs):  Introduction to the Radio Frequency Spectrum and Spectrum Management (RFS)
HLSI-03 (0.3 CEUs):  Methods for Smart Control of Spectrum Agile Radio Frequency Systems (MSC)
HLSI-04 (0.7 CEUs):  Controller Implementation for Spectrum Agility (ISA)

Course resources:

  • Ungraded pre-quizzes for each module in courses HLSI-01 – HLSI-03.
  • Narrated slide presentations with closed captioning
  • Downloadable 2- and 3-per-page slide handouts
  • Video demonstrations produced using software defined radio (SDR) software and testbeds
  • Supplemental text notes
  • Interactive simulation exercises that let students observe changes in radio link performance in response to manual and participant-programmed control of transmission parameters
  • Links to external videos, simulations, and documents
  • Post-module graded quizzes or self-reflections as well as pre- and post-course surveys to help you assess knowledge gained and help us improve the courses and simulations
