Online waveform selection for cognitive radar
Thulasi Tholeti, Avinash Rangarajan, Sheetal Kalyani
Designing a cognitive radar system capable of adapting its parameters is challenging, particularly when tasked with tracking a ballistic missile throughout its entire flight. In th…
Source Enumeration using the Distribution of Angles: A Robust and Parameter-Free Approach
Gokularam Muthukrishnan, Siva Shanmugam, Sheetal Kalyani
Source enumeration, the task of estimating the number of sources from the signal received by the array of antennas, is a critical problem in array signal processing. Numerous metho…
BayesAoA: A Bayesian method for Computation Efficient Angle of Arrival Estimation
Akshay Sharma, Nancy Nayak, Sheetal Kalyani
The angle of Arrival (AoA) estimation is of great interest in modern communication systems. Traditional maximum likelihood-based iterative algorithms are sensitive to initializatio…
Airplane-Aided Integrated Next-Generation Networking
Muralikrishnan Srinivasan, Sarath Gopi, Sheetal Kalyani +2
A high-rate yet low-cost air-to-ground (A2G) communication backbone is conceived for integrating the space and terrestrial network by harnessing the opportunistic assistance of the…
Intelligent Reflecting Surface Assisted Beam Index-Modulation for Millimeter Wave Communication
Sarath Gopi, Sheetal Kalyani, Lajos Hanzo
Millimeter wave communication is eminently suitable for high-rate wireless systems, which may be beneficially amalgamated with intelligent reflecting surfaces (IRS), relying on bea…
Deep Reinforcement Learning based Blind mmWave MIMO Beam Alignment
Vishnu Raj, Nancy Nayak, Sheetal Kalyani
Directional beamforming is a crucial component for realizing robust wireless communication systems using millimeter wave (mmWave) technology. Beam alignment using brute-force searc…
