Research

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
