SPARSE LINEARIZATION AND HARDWARE FOR 5G AND BEYOND

Research Project, 2021 – 2023

urpose and goal: The overall goal with this project is the development of power amplifier linearization schemes and novel hardware, operating at extreme bandwidth in massive multi-antenna 5G, and beyond, systems Sub-objectives:
* Design of hardware to exploit "sparsity", i.e. high-bandwidth signals with multiple narrowband components. * Wideband linearization based on sparsity in freuency and geografically (the terminals are at a few unique positions at each moment). * Demonstrate wideband multi-antenna linearization in a testbed, operating in a realistic environment. Expected results and effects: A successful project will provide solutions that keep Swedish industry ahead in the area of telecommunication. * The focus on linearization and energy-efficient amplifiers, which is probably the single most important technique for energy-efficient base stations, will contribute to sustainable development, energy savings and environment-friendly telecommunication networks. * It keeps Ericsson and Bluetest ahead in telecom through the development and testing of modern efficient base stations * Ericsson´s and Bluetest´s international competitiveness will be strengthened.
