Prof. Ranjit Gharpurey, along with a colleague, Prof. J. C. Rudell from the University of Washington, has received a 3-year grant from the National Science Foundation. A key aspect of this research effort will be an investigation of circuits and architectures for frequency-agile broadband radio transceivers, including half and full-duplex radio systems, with the goal of minimizing hardware overhead and complexity. The effort 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.
