Sub Terahertz LEO Satellite Communication: Vision, Opportunities, and Challenges toward the First Prototype in Space
Sergi Aliaga, Vitaly Petrov, Andrew Benincasa +7
The landscape of sub-terahertz (sub-THz, 100GHz - 300GHz) wireless technology evolved drastically over the last two decades - from only a few niche use cases in sensing and ultra-s…
Topology-Aware Two-Stage Federated Learning via Proxy Models for Sub-THz Heterogeneous LEO Communications
Jinhao Yi, Weijun Gao, Chong Han +2
Federated learning (FL) has emerged as a promising distributed training paradigm for Low Earth Orbit (LEO) networks by significantly reducing communication overhead. However, its d…
Toward the Internet of Space Things: Performance Analysis of LEO Satellite Relay Networks using mmWave and sub-THz links
Sergi Aliaga, Ahmad Masihi, Vitaly Petrov +2
As the commercial space economy expands, existing ground-based infrastructure faces severe bottlenecks in supporting the data-intensive continuous connectivity needs of next-genera…
User Mobility Demands Near-Field Communications in Terahertz Band Wireless Networks Beyond 6G
Peng Zhang, Vitaly Petrov, Arjun Singh +2
Near-field propagation is often unavoidable at terahertz (THz) frequencies due to the large apertures needed for sufficient array gain, yet near-field operation complicates practic…
On the Spatial Consistency of Sub-Terahertz Channel Characteristics for Beyond-6G Systems
Hossein Amininasab, Huda Farooqui, Dmitri Moltchanov +4
Ray tracing is a versatile approach for precise sub-terahertz (sub-THz, 100-300 GHz) channel modeling when designing new mechanisms for beyond-6G cellular systems. Theoretically, w…
Multipath Channel Metrics and Detection in Vascular Molecular Communication: A Wireless-Inspired Perspective
Timo Jakumeit, Lukas Brand, Josep M. Jornet +3
Motivated by classical communications engineering, early works in molecular communication (MC) largely adopted established modeling and signal processing concepts from wireless ele…
