A relentless trend in wireless communications is the hunger for bandwidth, and fresh
bandwidth is only to be found at ever higher frequencies. While 5G systems are seizing the …

Thanks to the abrupt advances in semiconductor technologies, particularly in terms of the
operating frequency, the last decade has seen various efforts and trials in attempts to …

This paper establishes an upper bound on the capacity of line-of-sight multiantenna
channels over all possible antenna arrangements and shows that uniform linear arrays …

Long-range E-band communication with fiber-equivalent speed is emerging extensively as a
critical technology in the next-generation communication. This paper firstly reviews the …

This paper deals with line-of-sight (LOS) MIMO communication via an intelligent reflecting
surface (IRS). It is shown that the number of spatial degrees of freedom (DOF) afforded by …

In this article, we present our vision for how extremely large aperture arrays, equipped with
hundreds or thousands of antennas, can play a major role in future 6G networks by enabling …

Motivated by the widespread adoption of the parabolic wavefront model for line-of-sight
(LOS) multiple-input multiple-output (MIMO) communication, this paper presents a …

Multiple-input multiple-output has been a key technology for wireless systems for decades.
For typical MIMO communication systems, antenna array elements are usually separated by …

This paper provides a deterministic channel model for a scenario where wireless
connectivity is established through a reflection off a smooth planar surface of an infinite …

Sixth generation (6G) wireless networks are envisioned to include aspects of energy
footprint reduction (sustainability), besides those of network capacity and connectivity, at the …
