Sub-terahertz (Sub-THz) technology, as one of the key candidates for the six generation (6G) systems, has attracted increasing attention from academia and […]
Enabling Long-Range Large-Scale Channel Sounding at Sub-THz Bands: Virtual Array and Radio-Over-Fiber Concepts
Sub-terahertz (sub-THz) (i.e., 100–300 GHz) communication is envisaged as one of the key building blocks for future communication systems due to its […]
Coupling machine learning and physical modelling for predicting runoff at catchment scale
In this paper, we present an approach that combines data-driven and physical modelling for predicting the runoff occurrence and volume at catchment […]
Channel Scheduling for IoT Access with Spatial Correlation
Spatially correlated device activation is a typical feature of the Internet of Things (IoT). This motivates the development of channel scheduling (CS) […]
