Next-generation cellular technologies, commonly referred to as the sixth generation (6G),
are envisioned to support a higher system capacity, better performance, and network …

The exploitation of the substantial bandwidths available in the terahertz (THz) band has
recently attracted considerable interest. However, beam squint effect is a significant obstacle …

Beam Squint is one of the major problems that affects terahertz (THz) wideband
beamformers and degrades their performance. With the aim of compensating this effect …

We propose in this paper a novel hierarchical multi-grid orthogonal matching pursuit based
angle estimation scheme. The proposed scheme accurately estimates the angles of …

This paper presents an optimization approach for static antenna array thinning using a
genetic algorithm (GA). The goal is to reduce hardware complexity while maintaining a …
