Single-Anchor Two-Way Localization Bounds for 5G mmWave Systems
Zohair Abu-Shaban, Henk Wymeersch, Thushara Abhayapala +1
Recently, millimeter-wave (mmWave) 5G localization has been shown to be to provide centimeter-level accuracy, lending itself to many location-aware applications, e.g., connected au…
Error Bounds for Uplink and Downlink 3D Localization in 5G mmWave Systems
Zohair Abu-Shaban, Xiangyun Zhou, Thushara Abhayapala +2
Location-aware communication systems are expected to play a pivotal part in the next generation of mobile communication networks. Therefore, there is a need to understand the local…
Artificial-Noise-Aided Secure Transmission in Wiretap Channels with Transmitter-Side Correlation
Shihao Yan, Xiangyun Zhou, Nan Yang +2
This work for the first time examines the impact of transmitter-side correlation on the artificial-noise-aided secure transmission, based on which a new power allocation strategy f…
Achieving secrecy without knowing the number of eavesdropper antennas
Biao He, Xiangyun Zhou, Thushara D. Abhayapala
The existing research on physical layer security commonly assumes the number of eavesdropper antennas to be known. Although this assumption allows one to easily compute the achieva…
Band Limited Signals Observed Over Finite Spatial and Temporal Windows: An Upper Bound to Signal Degrees of Freedom
Farhana Bashar, S. M. Akramus Salehin, Thushara D. Abhayapala
The study of degrees of freedom of signals observed within spatially diverse broadband multipath fields is an area of ongoing investigation and has a wide range of applications, in…
Analysis of Degrees of Freedom of Wideband Random Multipath Fields Observed Over Time and Space Windows
Farhana Bashar, S. M. Akramus Salehin, Thushara D. Abhayapala
In multipath systems, available degrees of freedom can be considered as a key performance indicator, since the channel capacity grows linearly with the available degrees of freedom…
