HoloBeam: Learning Optimal Beamforming in Far-Field Holographic Metasurface Transceivers

no code implementations30 Dec 2023 Debamita Ghosh, Manjesh Kumar Hanawal, Nikola Zlatanova

To overcome this, {\it\HB} works with the discrete values of phase-shifting parameters and exploits their unimodal relations with channel gains to learn the optimal values faster.

UB3: Best Beam Identification in Millimeter Wave Systems via Pure Exploration Unimodal Bandits

no code implementations26 Dec 2022 Debamita Ghosh, Haseen Rahman, Manjesh K. Hanawal, Nikola Zlatanov

In this paper, we develop an algorithm that exploits the unimodal structure of the received signal strengths of the beams to identify the best beam in a finite time using pure exploration strategies.

Learning Optimal Phase-Shifts of Holographic Metasurface Transceivers

no code implementations12 Dec 2022 Debamita Ghosh, Manjesh K. Hanawal, Nikola Zlatanov

Holographic metasurface transceivers (HMT) is an emerging technology for enhancing the coverage and rate of wireless communication systems.

Parametric Channel Model Estimation for Large Intelligent Surface-Based Transceiver-assisted Communication System

no code implementations5 Apr 2022 Debamita Ghosh, Manjesh Kr. Hanawal, Nikola Zlatanov

A promising approach for enhancing the coverage and rate of wireless communication systems is the large intelligent surface-based transceiver (LISBT), which uses a spatially continuous surface for signal transmission and receiving.

Learning to Optimize Energy Efficiency in Energy Harvesting Wireless Sensor Networks

no code implementations30 Dec 2020 Debamita Ghosh, Manjesh K. Hanawal, Nikola Zlatanov

We study wireless power transmission by an energy source to multiple energy harvesting nodes with the aim to maximize the energy efficiency.

Learning and Fairness in Energy Harvesting: A Maximin Multi-Armed Bandits Approach

no code implementations13 Mar 2020 Debamita Ghosh, Arun Verma, Manjesh K. Hanawal

It is thus important to learn the least amount of energy harvested by nodes so that the source can transmit on a frequency band that maximizes this amount.
