Rudell Receives NSF Funding to Advance Work on Broadband Radio Transceivers

UW EE Assistant Professor Chris Rudell, and Professor R. Gharpurey of the University of Texas, have received a three-year grant from the National Science Foundation. The goal of this research is to minimize hardware overhead and complexity by exploring circuits and architectures for frequency-agile broadband radio transceivers, including half and full-duplex radio systems. Research efforts will also address techniques for enhancing interference immunity of broadband radio front-ends and transmitter architectures that attenuate out-of-band spectral emissions in order to address co-existence challenges.

The designs will be engineered to meet high data-rate needs of current and emerging wireless standards by enabling devices that allow for flexible, and reconfigurable use of spectrum. Practical viability of the proposed approaches will be verified by means of integrated circuit implementations in standard CMOS technologies.
