Course Description

Wireless systems are deeply embedded in our everyday lives, changing how we communicate and sense our surroundings. Demand for ubiquitous wireless systems is growing rapidly with the rise of autonomous systems, and wireless systems are moving toward merging communication and sensing into a single platform with shared hardware, waveforms, and spectrum. This course will cover the fundamentals of wireless and radar communication systems, including transceivers, waveforms, and protocols. Then, we will cover recent advances in integrating sensing and communication (ISAC) and discuss the major open challenges of ISAC: hardware sharing, waveform sharing, and applications. A goal of the course is to expose students to emerging system designs and to develop their ability to critically evaluate which technologies are promising candidates for future wireless systems so they can come up with their own research ideas at the intersection of sensing and communication. The course will emphasize hardware and software co-design, prototyping, and implementation, and includes a series of student project presentations and a final demonstration.

Prerequisites

Graduate standing in Electrical and Computer Engineering or a related field. Students should be comfortable with signals and systems, probabilities, and linear algebra. Prior exposure to a undergraduate-level course in wireless communications, digital communications, or a related course is recommended.

Course Topics

  • Fundamentals of Wireless Communication Systems
  • Fundamentals of Radar Systems
  • ISAC Systems: Challenges, Design Considerations, and Applications

Course Policies and Resources

Academic Integrity

You are encouraged to discuss paper assignments and projects with classmates, but all collected data, analysis, images, graphs, and other written work must be your own. For the final project, you have full access to the web, but any ideas, data, or code fragments drawn from other sources must be cited in accordance with standard academic practice. Students caught cheating will automatically fail the course and be reported to the university. When in doubt about the ethics of any action, consult the departmental guidelines and/or ask. Ignoring the rules will not shield you from the consequences.

Students with Disabilities

The University of Texas at Austin offers reasonable academic adjustments to qualified students with disabilities upon request. To arrange accommodations, contact Disability and Access (D&A) through the Division of Diversity and Community Engagement at the Student Services Building (SSB), 471-6259, http://diversity.utexas.edu/disability/.

Religious Holy Days

Religious holidays sometimes conflict with class and examination schedules. If you miss an examination, presentation, or other project due to the observance of a religious holy day, you will be given the opportunity to complete the missed work within a reasonable time after the absence. Per University of Texas at Austin policy, you must notify each of your instructors at least fourteen days before the class dates you will miss to observe a religious holy day.

Updates to the Course

Course schedule may be subject to change with early notice.
