Angle-Resolved THz Channel Measurements at 300 GHz in a Shopping Mall Scenario

Alper Schultze, Wilhelm Keusgen, Michael Peter, Ramez Askar, Taro Eichler

This paper presents first results of channel measurements conducted at 300GHz in a shopping mall scenario. Angle-resolved channel impulse responses were analysed with regards to channel parameters. A novelty of this work is the channel parameter...

Superiorized Adaptive Projected Subgradient Method with Application to MIMO Detection

Jochen Fink, Slawomir Stanczak, Renato L. G. Cavalcante

This paper establishes the bounded perturbation resilience of the adaptive projected subgradient method (APSM), a flexible convex optimization framework. Exploiting this property enables a vast variety of heuristic extensions of APSM-based...

MIMO Systems with Reconfigurable Antennas: Joint Channel Estimation and Mode Selection

Fariba Armandoust, Ehsan Tohidi, Martin Kasparick, Li Wang, Ahmet Hasim Gokceoglu, Slawomir Stanczak

In this paper, we develop a low-complexity iterative mode selection algorithm for data transmission in a Reconfigurable antennas (RAs) MIMO system. Furthermore, we study channel estimation of an RA multi-user MIMO system. We propose a mode...
