A wideband generalization of the near-field region for extremely large phased-arrays
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
The narrowband and far-field assumption in conventional wireless system design leads to a mismatch with the optimal beamforming required for wideband and near-field systems. This d…
Outdoor-to-Indoor 28 GHz Wireless Measurements in Manhattan: Path Loss, Environmental Effects, and 90% Coverage
Manav Kohli, Abhishek Adhikari, Gulnur Avci +12
Outdoor-to-indoor (OtI) signal propagation further challenges the already tight link budgets at millimeter-wave (mmWave). To gain insight into OtI mmWave scenarios at 28 GHz, we co…
Dense Urban Outdoor-Indoor Coverage from 3.5 to 28 GHz
Dipankar Shakya, Dmitry Chizhik, Jinfeng Du +2
In the US, people spend 87% of their time indoors and have an average of four connected devices per person (in 2020). As such, providing indoor coverage has always been a challenge…
Polar Coded Modulation via Hybrid Bit Labeling
Hanwen Yao, Jinfeng Du, Alexander Vardy
Bit-interleaved coded modulation (BICM) and multilevel coded modulation (MLC) are commonly used to combine polar codes with high order modulation. While BICM benefits from simple d…
Machine Learning-based Urban Canyon Path Loss Prediction using 28 GHz Manhattan Measurements
Ankit Gupta, Jinfeng Du, Dmitry Chizhik +2
Large bandwidth at mm-wave is crucial for 5G and beyond but the high path loss (PL) requires highly accurate PL prediction for network planning and optimization. Statistical models…
Sampling and Reconstructing Angular Domains with Uniform Arrays
Silvio Mandelli, Marcus Henninger, Jinfeng Du
The surge of massive antenna arrays in wireless networks calls for the adoption of analog/hybrid array solutions, where multiple antenna elements are driven by a common radio front…
