A Measurement-Based Spatially Consistent Channel Model for Distributed MIMO in Industrial Environments
Christian Nelson, Sara Willhammar, Fredrik Tufvesson
Future wireless communication systems are envisioned to support ultra-reliable and low-latency communication (URLLC), which will enable new applications such as compute offloading,…
On the Feasibility of Human Presence Detection Using Ceiling-Mounted Sub-THz Channel Sounding: Conference Room Measurement
Ali Al-Ameri, Xuesong Cai, Aleksei Fedorov +1
This paper presents a measurement-based investigation on the feasibility of human presence detection using a ceiling-mounted sub-THz channel sounder operating from 134 to 146~GHz.…
Vertical Sub-THz Channel Characterization: Sounder Implementation and Initial Measurements
Ali Al-Ameri, Xuesong Cai, Juan Sanchez +4
We present a measurement-based characterization of indoor vertical ceiling-to-ground sub-THz channels in the 136-144 GHz band, motivated by ceiling-mounted radio-unit deployments f…
Performance Analysis of Digital Beamforming mmWave MIMO with Low-Resolution DACs/ADCs
Faruk Pasic, Mariam Mussbah, Stefan Schwarz +3
Future wireless communications will rely on multiple-input multiple-output (MIMO) beamforming operating at millimeter wave (mmWave) frequency bands to deliver high data rates. To s…
Distributed MIMO Positioning: Fundamental Limit Analysis and User Tracking Framework Design
Yingjie Xu, Xuesong Cai, Ali Al-Ameri +2
This paper presents a comprehensive study on the 3D positioning capabilities in distributed multiple-input multiple-output (MIMO) systems. Unlike previous studies that mainly rely…
3D Cooperative User Tracking for Distributed Integrated Sensing and Communication
Yingjie Xu, Xuesong Cai, Michiel Sandra +2
As integrated sensing and communication (ISAC) becomes an integral part of 6G networks, distributed ISAC (DISAC) is expected to enhance both sensing and communication performance t…
