RIS in Indoor Environments: Benchmarking Against Ambient Propagation
Masoud Sadeghian, Andrea Pizzo, Angel Lozano
The improvements in received signal power brought about by a reflective intelligent surface (RIS) might be overstated if background propagation mechanisms such as reflections, scat…
Spectral vs Energy Efficiency in 6G: Impact of the Receiver Front-End
Angel Lozano, Sundeep Rangan
This article puts the spotlight on the receiver front-end (RFE), an integral part of any wireless device that information theory typically idealizes into a mere addition of noise.…
Hybrid Arrays: How Many RF Chains Are Required to Prevent Beam Squint?
Heedong Do, Namyoon Lee, Robert W. Heath +1
With increasing frequencies, bandwidths, and array apertures, the phenomenon of beam squint arises as a serious impairment to beamforming. Fully digital arrays with true time delay…
25 Years of Signal Processing Advances for Multiantenna Communications
Emil Björnson, Yonina C. Eldar, Erik G. Larsson +2
Wireless communication technology has progressed dramatically over the past 25 years, in terms of societal adoption as well as technical sophistication. In 1998, mobile phones were…
What Will 5G Be?
Jeffrey G. Andrews, Stefano Buzzi, Wan Choi +4
What will 5G be? What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken bac…
On the Overhead of Interference Alignment: Training, Feedback, and Cooperation
Omar El Ayach, Angel Lozano, Robert W. Heath
Interference alignment (IA) is a cooperative transmission strategy that, under some conditions, achieves the interference channel's maximum number of degrees of freedom. Realizing…
