Joint Activity Detection and Channel Estimation for Massive IoT Access Based on Millimeter-Wave/Terahertz Multi-Panel Massive MIMO
Hanlin Xiu, Zhen Gao, Anwen Liao +5
The multi-panel array, as a state-of-the-art antenna-in-package technology, is very suitable for millimeter-wave (mmWave)/terahertz (THz) systems, due to its low-cost deployment an…
A Novel SCA-Based Method for Beamforming Optimization in IRS/RIS-Assisted MU-MISO Downlink
Vaibhav Kumar, Rui Zhang, Marco Di Renzo +1
In this letter, we consider the fundamental problem of jointly designing the transmit beamformers and the phase-shifts of the intelligent reflecting surface (IRS) / reconfigurable…
Intelligent Omni-Surfaces (IOSs) for the MIMO Broadcast Channel
Abdelhamed Mohamed, Nemanja Stefan Perović, Marco Di Renzo
In this paper, we consider intelligent omni-surfaces (IOSs), which are capable of simultaneously reflecting and refracting electromagnetic waves. We focus our attention on the mult…
