Characterization of mm-Wave Channel Sounders up to W-Band and Validation of Measurement Results

In this paper, the characterization of mm-wave channel sounders and validation of measurement data are discussed. Suitable procedures and metrics like the dynamic range and the maximum measurable path loss are proposed for this purpose. They are illustrated by using measurement data at 28 and 82GHz from back-to-back measurements in the laboratory as well as…

Estimation of DoA Based on Large-scale Virtual Array Data

Future 5G communication systems operating in the mmwave bands (6-100 GHz) will rely on multi-antenna techniques like beamforming and MIMO 1. Therefore, measurement and description of spatial channel information (direction of arrival DoA, direction of departure DoD) is of high relevance for mm-wave system design and channel modeling.
