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, ...
