Green and Smart Communications with Energy Harvesting: A Signal Processing Approach
Green and Smart Communications with Energy Harvesting: A Signal Processing Approach
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 654123.
Background: Communication Systems with Energy Harvesting (EH) Capabilities
Efficient usage of energy resources is a growing concern in today's communication systems. Solutions that consider energy harvesting (for instance harvesting energy from man made RF signals) instead of completely relying on a fixed battery or the power from the grid, offer a promising perspective. Such approaches have a wide range of applications including internet of things, machine-type communications, wireless sensor networks, smart homes and smart cities.
Main Concern: re-design of communication protocols
When one incorporates energy harvesting capabilities into a communication system, communication strategies have to be re-designed.
Understanding the information transfer capabilities of communication systems with energy harvesting features have been the attention of a number of recent works. At the moment the main line of research on the subject is typically done in an information theoretic framework. This line of work is important for understanding the fundamental limits in energy harvesting systems, yet it falls short in applicability in the context of practical scenarios.
Our approach:
We consider the question of how to communicate in systems with EH capabilities and focus on practical solutions. Practical receiver structures with linear filtering, low complexity designs such as linear precoders, power allocation methods are the main ingredients in our work. Our aim is to complement the existing information theoretic solutions, and contribute to creating future green and smart communication systems.
A simplified communication system. Our focus is on linear precoder and receiver filter design.
