Cognitive Radio for Asymmetric Cellular Downlink with Multi-User MIMO
Omer Gokalp Serbetci, Lei Chu, Andreas F. Molisch
Cognitive radio (CR) is an important technique for improving spectral efficiency, letting a secondary system operate in a wireless spectrum when the primary system does not make us…
Ultra-Wideband Double-Directional Channel Measurements and Statistical Modeling in Urban Microcellular Environments for the Upper-Midband/FR3
Naveed A. Abbasi, Kelvin Arana, Siddhant Singh +7
The upper midband, designated as Frequency Range 3 (FR3), is increasingly critical for the next-generation of wireless networks. Channel propagation measurements and their statisti…
Ultra-wideband Double-Directionally Resolved Channel Measurements of Line-of-Sight Microcellular Scenarios in the Upper Mid-band
Naveed A. Abbasi, Kelvin Arana, Jorge Gomez-Ponce +7
The growing demand for higher data rates and expanded bandwidth is driving the exploration of new frequency ranges, including the upper mid-band spectrum (6-24 GHz), which is a pro…
Context-Conditioned Spatio-Temporal Predictive Learning for Reliable V2V Channel Prediction
Lei Chu, Daoud Burghal, Rui Wang +2
Achieving reliable multidimensional Vehicle-to-Vehicle (V2V) channel state information (CSI) prediction is both challenging and crucial for optimizing downstream tasks that depend…
Wireless Channel Aware Data Augmentation Methods for Deep Learning-Based Indoor Localization
Omer Gokalp Serbetci, Daoud Burghal, Andreas F. Molisch
Indoor localization is a challenging problem that - unlike outdoor localization - lacks a universal and robust solution. Machine Learning (ML), particularly Deep Learning (DL), met…
