Positive Experience Keeps Arnett at KU for Grad School


(04-30-2010)

While Austin Arnett visited and was accepted to Stanford and the University of California, Berkeley, he chose to attend the University of Kansas. It is a decision he would make all over again. In fact, he is. Arnett, who is graduating with honors in EE this May, will begin graduate school at KU this fall. He will focus on radar systems as he pursues a masters degree in EE.

"It has been a really good experience, which is why I am coming back," says the El Dorado native. "My professors have been a great resource."

Arnett points to KUs outstanding facilities, especially Eaton Hall with its state-of-the-art classrooms and laboratories. Among his favorite classes were EECS 622 (Hardware Design) and EECS 502 (Senior design Lab). The former introduces the fundamentals of radio transmission systems, including wireless communication devices and radar. Arnett designed a radio transmission system to meet a given specification. In the Senior Design Lab, Arnett says students must use pieces of each core class to build a system. His team is designing and building an ultrasonic location and tracking system that uses a speaker to transmit two ultrasonic tones at known frequencies. They process the signals from each receiver and use the difference in phase information of each received signal to locate its exact position.

He says KU was the "best and most affordable option" for him. He received a Summerfield Scholarship as well as renewable scholarships from Garmin, EECS and the School of engineering. An interest in math, science and problem solving led him to EE. Radios and radar have become focus areas for Arnett.

At KUs Information and Telecommunication Technology Center (ITTC), Arnett is conducting research on radar-embedded communication for his honors project. There is a great need for a reliable covert communication system for soldiers in hostile territory. Too often, eavesdroppers can intercept messages. EECS Assistant Professor Shannon Blunt is developing technology that will enable soldiers messages to"piggyback" on existing radar signals. Current covert communication of this type requires hundreds of radar pulses to convey just one communication symbol thus resulting in very low data rates. In contrast, Blunts team embeds a communication symbol into each individual radar pulse. Preliminary results suggest the potential for operation at data rates 1,000 times faster than current radar-embedded communication systems while offering at least the same level of security.

"I am looking into the practical implementation of radar-embedded-communication (REC) theory. Up to now, there have only been computer simulations done to evaluate and test REC ideas," says Arnett. "I am using an actual radar system in ITTCs Radar and Remote Sensing Lab (RSL) to implement and explore challenges faced during implementation."

"I have been very impressed with Austins willingness to go after an unconventional problem," says Blunt, Arnetts advisor. "He has also demonstrated the ability to work independently towards a solution. These are the hallmarks of a good researcher."

In addition to being an honor student, Arnett was a member of Phi Kappa Psi fraternity and KU Bowling Team. He served as president during the 2009-2010 bowling season. He notes that KU is a huge campus with numerous clubs and activities. Arnett says it is important to find things you enjoy and get involved.

"Be proactive and do things ahead of time," says Arnett when asked what advice he would give to students. "Managing your time is important."

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
