RF front-end for digital communications:

Modelization of RF circuits (non-linear, large band, noisy, reconfigurable...)
Sizing and Modelization of entire transmission chains including the RF front-end to analyze the performances:
- application to wireless communications
- application to RF interconnects on a SoC
- use of complex signals like multi-carriers ones, characterized by a variable envelop
Development of new circuits and systems according to the application : new agile multi-bands synthesizer, multistandard emitter

Dirty RF:

The concept of “Dirty RF” allows to deal with RF imperfections by adding numerical processing to mitigate their effects. We propose such treatment for:

Linearization, efficient improvement
I/Q imbalance compensation
Interference reduction
Mis-synchronisation

Applications to “Software Defined Radio” and “Green Radio”.
