Building a Better Cellphone
Electrical Engineering Society Recognizes Prof’s Work on Wireless Technology
If you’ve ever wished your cellphone had greater range, better sound quality and longer battery life, then rest assured Dr. Aria Nosratinia is doing what he can to make your dream come true.
And for his efforts, the UT Dallas professor has been named an IEEE fellow, one of the highest honors bestowed by the Institute of Electrical and Electronics Engineers.
The tribute recognizes him for more than 10 years of work in communication and information theory, particularly his ongoing work on what’s known as cooperative wireless communications.
“This is a method that essentially extends the range or quality of wireless communication, reduces the use of battery power, or a combination of the above,” said Nosratinia, a professor of electrical engineering in the Erik Jonsson School of Engineering and Computer Science at UT Dallas. “In particular, my group has developed what is known as coded cooperation, which has become a hot topic of research and has been cited by hundreds of other research works.”
In coded cooperation, two wireless devices jointly transmit their signals using both of their antennas, resulting in improved voice clarity, higher data rates, lower transmit power and longer battery life.
Cooperative wireless technology is expected to be an important element in next-generation wireless communications.
Nosratinia, who is also director of the Jonsson School’s Multimedia Communications Laboratory, is the 13th member of the school’s faculty to be named an IEEE fellow, a designation granted each year to only a select group of the organization’s 370,000 members who have exhibited “an extraordinary record of accomplishments.”
He is also well-known for earlier research in image and video processing.
“Some of my work on removing the artifacts of image compression remains state-of-the-art to this day,” he said. “This class of work allows images and video to be compressed heavily and yet be upgraded at the receiving end to a higher quality level than was previously thought possible.”
While his cooperative communication research continues to advance, his research group is also active in functional magnetic resonance imaging, where he hopes recent results will translate into more efficient algorithms for medical diagnostics.
Nosratinia received his Ph.D. in electrical and computer engineering from the University of Illinois at Urbana-Champaign and held visiting appointments at Princeton University, Rice University and UCLA prior to joining UT Dallas in 1999.
IEEE is the world’s leading professional organization and standards-setting authority for a wide range of high-tech fields, including electrical engineering, aerospace systems, computer engineering, telecommunications and biomedical engineering.
