"DIDO Behavioural Model Extraction Setup Using Uncorrelated Envelope Signals", a work by Hossein Zargar, Ali Banai and José C. Pedro, won the best paper award in the European Microwave Conference, EuMC Microwave Prize. This is the second best conference in the area of RF and microwave technics.

Behavioural models - the mathematical representation of the performance of wireless systems - are the result of a compromise between complexity, accuracy and easiness of identification of this performance in the laboratory. These models can be very useful when the component is used in an environment similar to the one used to define it in the lab.
However, environments can change continuously in unpredictable ways, degrading substantially this accuracy.

DIDO - double-input/double-output appears to replace the traditional SISO-single-input/single-output format, in which the transmitted signal is not only dependent on the driving information but also on the reflections generated in the terminations. Unfortunately, laboratories are not equipped for this change. This work demonstrates that the DIDO model is much more than an elegant mathematical formulation since it can be identified through real measurements in a microwave lab. For that, several measurement setups and model identification methodologies were discussed and tested, proving that the proposed DIDO model is indeed capable to cope with the variations of the amplifier terminations with little accuracy degradation.

The ceremony took place in Paris, during the EU Microwave Week 2015, from 6 to 11 September.
