Research Interests
My current expertise and research interests are in the general areas of communication and information
transmission systems with focus on:
- Wireless communication systems and networks,
- Communication and information theory,
- Digital signal processing.
In recent years I have worked on:
- Software defined radio platforms for implementing versatile communication systems.
- Blind signal detection/classification for signal intelligence (SIGINT) and spectrum sensing in
cognitive radio systems using signal processing and machine learning.
- Waveform and receiver filter design for interference mitigation, efficient spectrum utilization, and dynamic
spectrum access in wireless communication systems.
- Internet of Things (IoT) and cyber-physical systems (CPS), designing IoT gateways and roadside units for
vehicular ad-hoc networks (VANETs) and intelligent transportation systems (ITS), integration of cyber- and physical
components for small size spacecraft systems (CubeSats, sounding rocket payloads, etc.).
- Multiple antennas/MIMO systems, beamforming, distributed antenna systems (DAS).
- OFDM and multi-carrier modulation
- Algorithms for signal processing and spectrum estimation(Kalman/Wiener filtering, gradient/steepest
descent, recursive least-squares, array signal processing, compressive sensing, etc.).
During my graduate studies at Rutgers University I was part of the Wireless Information Network Laboratory
WINLAB and I have also worked on
- Optimal sequences and codeword optimization for CDMA systems
- Interference avoidance/suppression and power control in wireless systems
- Communication over fading and dispersive channels
- Wireless communications in unlicensed bands
- Kalman filtering and applications to communications and signal processing
- Extended Kalman filtering for emitter localization based on time difference of arrival (TDOA)
- Optimal control and filtering for deterministic and stochastic systems
- Speech processing
- Neural networks with applications to control and signal processing
My graduate research on "Interference avoidance and dispersive channels: a new look at multicarrier modulation"
was awarded 2nd prize in the AT&T Student Research Day (ACM Competition), in October 1999, held at the
AT&T Shannon Laboratory in Florham Park, New Jersey).
Other projects on which I have worked on as a graduate student at Rutgers University include:
- Reverse link simulator for W-CDMA systems, during my Summer 2000 internship with Telcordia Technologies
(formerly known as Bell Communications research - Bellcore until 1999 and acquired by Ericsson in 2015)
- Kalman filtering of colored noise for speech enhancement and recognition, during my Summer 1997 internship
with AT&T Labs).
- Neural network modeling and control of food extrusion processes, with the Center for Advanced Information
Processing (CAIP) and the Center for Advanced Food Technology (CAFT) at Rutgers
University (1998-99).
- Optimal control and filtering for singularly perturbed and biased systems
- Robust control techniques for multivariable systems
