Beam Squint Effects in THz Communications with UPA and ULA: Comparison and Hybrid Beamforming Design
Publikováno v:
2022 IEEE Globecom Workshops (GC Wkshps).
Future 6G and beyond wireless systems aim at ultra-high data rates from very large bandwidths in millimeter-wave and terahertz bands. Large bandwidth signals in antenna arrays lead to beam squint or frequency-selective array response causing losses i

The stochastic geometry is a powerful tool to model spatial network-level problems. One such application of the stochastic geometry is to model the interference in wireless communication networks. This chapter gives basics of the stochastic modelling

The terahertz band, 0.1–10 THz, has sufficient resources not only to satisfy the 5G requirements of 10 Gb/s peak data rate but to enable a number of tempting rate-greedy applications. However, the terahertz band brings novel challenges, never addre

We present some preliminary measurement results for the reflection properties of common indoor materials for 300 and 1000 GHz frequencies. These material include various wooden surfaces, concrete, rubber floor surface, and glass. All the presented ma

This thesis focuses on THz band channel modeling and characterization. This vast frequency band spans from 100 GHz to 10 THz. The approximately 10,000 GHz bandwidth together with advances in THz capable electronics have made this band highly potentia

This paper documents a simple parametric polynomial line-of-sight channel model for 100-450 GHz band. The band comprises two popular beyond fifth generation (B5G) frequency bands, namely, the D band (110-170 GHz) and the low-THz band (around 275-325
