Research
My research interests are broadly in the areas of
adaptive signal processing and wireless communications systems, with an
emphasis on various transceiver algorithms for block modulated cellular systems.
A significant portion of these research activities have been done in
collaboration with many of my colleagues in the TeNeT group, including
(in chronological order)
Prof. Bhaskar Ramamurthi,
Prof. Devendra Jalihal, Prof. Ashok Jhunjhunwala, Prof. R. Aravind,
Prof. David Koilpillai, Prof. Srikrishna Bhashyam, Prof. Andrew Thangaraj,
Prof. Sheetal Kalyani, Prof. Radhakrishna Ganti, Prof. Gaurav Raina, and
Prof. Nitin Chandrachoodan. .
Particular R&D topics include:
- Simulataneous Spectrum Sharing (Non-orthogonal sharing) by Multiple Operators in the sub 1GHz bands
- Desinging new user admission control, rate-adaptation, and QoS aware scheduling for such
non-orthogonal air interface, monitor some notions of "fairness" of spectrum sharing among
the licensed operators
- Co-channel Interference Management -- Advanced Fractional Reuse Techniques, Novel Joint Receivers
- Working with Mis-specified Statistics -- Robust Statistics for Estimation & Detection
- Applications of Game Theory and Quantum Estimation to Broadband Cellular Networks
- Very Wideband Receivers for Strategic Applications -- Using Signal Processing to avoid Jammer-related issues
- New 5G Waveforms for Ultra-reliable (possibly non-synchronous) Uplinks with low PAPR
- Performance Analysis of Broadband Cellular Networks
- 5G Testbed development (including non-orthogonal sharing technology demonstrator)
