Twenty-Five Years of Advances in Beamforming: From Convex and Nonconvex Optimization to Learning Techniques
Ahmet M. Elbir, Kumar Vijay Mishra, Sergiy A. Vorobyov +1
Beamforming is a signal processing technique to steer, shape, and focus an electromagnetic wave using an array of sensors toward a desired direction. It has been used in several en…
A Unified Approach for Beam-Split Mitigation in Terahertz Wideband Hybrid Beamforming
Ahmet M. Elbir
The sixth generation networks envision the deployment of terahertz (THz) band as one of the key enabling property thanks to its abundant bandwidth. However, the ultra-wide bandwidt…
Federated Channel Learning for Intelligent Reflecting Surfaces With Fewer Pilot Signals
Ahmet M. Elbir, Sinem Coleri, Kumar Vijay Mishra
Channel estimation is a critical task in intelligent reflecting surface (IRS)-assisted wireless systems due to the uncertainties imposed by environment dynamics and rapid changes i…
The Rise of Intelligent Reflecting Surfaces in Integrated Sensing and Communications Paradigms
Ahmet M. Elbir, Kumar Vijay Mishra, M. R. Bhavani Shankar +1
The intelligent reflecting surface (IRS) alters the behavior of wireless media and, consequently, has potential to improve the performance and reliability of wireless systems such…
