My Research Work

"To go fast, go alone. To go far, go together!"

 
Research Interests

My research interests are related to the design of smart green wireless communication systems. This includes the design of high efficiency radio frequency transmitters, and the development of appropriate system level architectures and digital signal processing techniques that will enable the use of such systems in modern communication infrastructure.

Particularly, I am interested in:

  • Design of advanced power amplification systems: load modulation (Doherty), and drain modulation (envelope elimination and restoration "EER" and envelope tracking "ET"),...

  • Behavioural modelling of power amplifiers and transmitters: wideband models, memory effects extraction and modelling,...

  • Performance enhancement through digital signal processing: digital predistortion, crest factor reduction, ...
