WNCG team develops new antenna measurements and new knowledge for 60 GHz and above

July 25, 2011
WNCG Founder and UT's WICAT site director, Prof. Ted Rappaport, and Ph.D. students James Murdock, Felix Gutierrez, and Eshar Ben-Dor, recently published the paper titled 'Challenges and Approaches to On-chip Millimeter Wave Antenna Pattern Measurements' at the 2011 IEEE MTT-S International Microwave Symposium (IMS) in Baltimore, MD. The paper addresses challenges and offers several possible solutions to on-chip antenna measurements and wafer probe radiation removal, which are key issues that plauge the industry today.

WNCG EURECA Program in its 6th year

July 25, 2011
The EURECA program, an NSF funded undergraduate research experience for undergraduates (REU), commenced its 6th summer program on June 6th this year. A nine-week program led by Professors Bard and Vishwanath, it draws undergraduates from across the nation to participate in graduate-level cutting-edge research in networking, wireless, robotics, control and signal processing. This year's program has a special emphasis of bridging research and entrepreneurship for the program participants.

DELL provides super-server to WNCG

July 25, 2011
Through the generous support of Dell, Inc., a WNCG industrial affiliate sponsor, WNCG is now equipped with an enterprise-level computer server for complex circuit designs and electromagnetic field simulations. WNCG's new Dell PowerEdge T610 server provides 96GB of RAM memory, many terabytes of hard drive space, and 2 independent Intel Xeon quad-core processors to run complex simulations of millimeter-wave integrated circuits, antennas, and layout designs using; ANSYS HFSS, ADS, Cadence, and other software tools.

WNCG Team to implement on-chip Sub-THz Antennas for DARPA

July 25, 2011
WNCG Ph.D. students James Murdock and Felix Gutierrez, working with Professors Ted Rappaport, Deji Akinwande, and Arjang Hassibi, will be developing a millimeter-wave on-chip antenna array and RF receiver circuitry in 45 nm IBM Silicon-on-Insulator (SOI) technology. As part of the Leading Edge Access Program (LEAP) by DARPA, WNCG researchers will work with other industry and government researchers, and will be given privileged access to state-of-the-art, onshore CMOS technology for the development of advanced concepts relevant to DoD problems.

WNCG Moving up to Sub-THz Frequencies with Rohde and Schwarz

July 25, 2011
Prof. Ted Rappaport's RFIC and Propagation Laboratory is acquiring a state-of-the art millimeter-wave measurement system up to 220 GHz provided by Rohde Schwarz. Rodhi Schwarz is an industry leader in test and measurement systems for baseband, analog, RF, millimeter-wave, and terahertz frequencies, and recently made a major commitment to help WNCG move its research capabilities above 100 GHz.

Interference Mitigation in Wireless OFDM Communication Systems

July 25, 2011
We have developed non-parametric interference mitigation methods for wireless orthogonal frequency division multiplexing (OFDM) receivers. The interference mitigation methods observe interference on the unused tones, reconstruct the interference from the sparse observations, and subtract the interference from the OFDM symbol. The methods can be used in any existing OFDM receiver, and achieve 5-10 dB of SNR gain in the presence of impulsive noise. Interference is a major limiting factor for communication performance in many wireless networks, esp. cellular, Wi-Fi, and ad hoc networks.

Jubin Jose Wins 2011 Student Leadership Award

July 25, 2011
Jubin Jose Wins 2001 Student Leadership Award' This year's winner of the WNCG student leadership award was Jubin Jose. Jubin has shown initiative and leadership in a number of areas important to WNCG, including student life, scholarship, and the WNCG organization itself. Perhaps most impressively, Jubin has been critical in revitalizing the WNCG student seminar series & a forum for our students to share ideas, and more importantly, to convey to one another the excitement for research, scholarship, and collegiality.
