My research interests are broadly in the areas of digital signal processing, information theory, estimation theory, and their applications in the optimization of MIMO wireless communication systems. Some of the projects I have worked on in the past are:
Transmit optimization/precoding in MIMO systems
CSI feedback schemes in MISO/MIMO systems
MIMO (semi-blind) channel estimation techniques
Channel feedback for OFDM
Tracking time varying channels in feedback based systems
Effect of estimation errors, feedback delay and channel errors on communication systems
Robust channel estimation in time division duplex (TDD) systems
Currently, I am interested in problems in:
Source coding and joint source-channel coding
MIMO/OFDM channel estimation
Cognitive radio
Energy harvesting based communications
Scheduling and resource allocation
Compressive sensing and sparse Bayesian learning
Interference management
