Pattern and Polarization Diversity Multi-Sector Annular Antenna for IoT Applications

no code implementations6 Jul 2023 Abel Zandamela, Nicola Marchetti, Max J. Ammann, Adam Narbudowicz

This work proposes a small pattern and polarization diversity multi-sector annular antenna with electrical size and profile of ${ka=1. 2}$ and ${0. 018\lambda}$, respectively.

Wavelet Packet Division Multiplexing (WPDM)-Aided Industrial WSNs

no code implementations28 May 2023 Indrakshi Dey, Nicola Marchetti

The central platform incorporates a decision fusion center (DFC) that arrives at global decisions regarding each set of phenomena by combining the received local sensor decisions.

IoT Localization and Optimized Topology Extraction Using Eigenvector Synchronization

no code implementations28 May 2023 Indrakshi Dey, Nicola Marchetti

Internet-of-Things (IoT) devices are low size, weight and power (SWaP), low complexity and include sensors, meters, wearables and trackers.

no code implementations20 Jan 2023 Abel Zandamela, Nicola Marchetti, Adam Narbudowicz

This work proposes an electrically small 3D beamforming antenna for PHYsical Layer (PHY-layer) security.

Energy-Efficient Physical Layer Security for Wearable IoT Devices

no code implementations15 Jan 2023 Abel Zandamela, Nicola Marchetti, Adam Narbudowicz

Furthermore, this work investigates the DM performance using a subset of the stacked patches in the MIMO antenna, revealing that some combinations achieve a low BER performance using a lower antenna profile, albeit high side-lobes of BER${<10^{-2}}$ seen outside the desired region.
