Honor Policy
Faculty in the ECE Department are committed to detecting and responding to all instances of scholastic dishonesty and will pursue cases of scholastic dishonesty in accordance with university policy. Scholastic dishonesty, in all its forms, is a blight on our entire academic community. All parties in our community -- faculty, staff, and students -- are responsible for creating an environment that educates outstanding engineers, and this goal entails excellence in technical skills, self-giving citizenry, and ethical integrity. Industry wants engineers who are competent and fully trustworthy, and both qualities must be developed day by day throughout an entire lifetime. Scholastic dishonesty includes, but is not limited to, cheating, plagiarism, collusion, falsifying academic records, or any act designed to give an unfair academic advantage to the student. Penalties for scholastic dishonesty are severe and can include, but are not limited to, a written reprimand, a zero on the assignment/exam, re-taking the exam in question, an F in the course, or expulsion from the University. Please do not jeopardize your career by an act of scholastic dishonesty. Details about academic integrity and what constitutes scholastic dishonesty can be found at the website for the UT Dean of Students Office and the General Information Catalog, Section 11-802.
Course Projects
Students shall
submit written pre-proposals with an early draft of their intended research interests by
February 12 at the beginning
of class. This pre-proposal should include a complete bibliography that identifies key technical journals, web sites, or standard bodies that are of interest to you,
and a detailed description of a few potential topics.
Student
proposals shall be presented and due in late February (February 26), during the class
period. Students shall have four free research days on February 10, April 9, April 16, and April 28,
and are invited to meet with me to discuss research topics, references, and cutting edge trends in wireless
communications throughout the semester. The written proposal shall be a 6 - 10 page typewritten document with
figures and a complete bibliography and literature search, demonstrating the student's current knowledge and
area of interest for the final project.
Proposals shall be presented in five-minute intervals during the
February 26 class.
Final presentations will be given in a symposium format during the last week of class.
Research topics should consist of a student's favorite area and may include the following suggested topics:
- MIMO
- OFDM Modulation
- Blast and V-Blast OFDM
- Current Emerging Wireless Standards
- WiMax and LTE
- Personal Area Networks
- Wigwam
- Software Defined Radios
- Broadcast Channels and Information Theory
- Cooperative Networking
- Other wireless topics that interest you
