Frequency Division Multiplexing Transmitter - A new energy efficient architecture for ultra-wideband wireless applications

Research Project, 2026 – 2030

This project aims to develop a novel energy-efficient transmitter architecture for wireless communication, called the Frequency Division Multiplexing Transmitter (FDMTX). By dividing wideband signals into multiple narrowband and efficient transmit branches that are combined at the output, the architecture enables improved energy efficiency, increased link capacity, and enhanced frequency and bandwidth agility.The research targets four main goals: analyzing combiner networks and power amplifier architectures, developing energy-efficient power amplifiers resilient to frequency-domain crosstalk, designing scalable digital linearization algorithms, and exploring ultimate performance limits for ultra-wideband communication.The project is carried out by a multidisciplinary team with expertise in microwave engineering, communication theory, and digital signal processing. It is structured into four work packages over four years, encompassing both theoretical analysis and experimental demonstrations.The proposed architecture has the potential to dramatically improve energy efficiency and link capacity for future communication systems. The results are expected to have a significant impact on the development of energy-efficient transmitters for both sub-6 GHz and mm-wave applications.
