Current activities, interests and expertise:
I have already devoted much of my research work
to the evolution of wireless communications from the second generation
(2G) to the third generation (3G). I am now interested in the transition
to the fourth generation (4G), in order to guarantee future access to the
high-speed wireless Internet. One of the challenges will be the support, at
low deployment costs, of multiple and variable transmission rates with different
qualities of service (voice, video, data).
I have developed an original technique for the detection of radio-frequency
signals over wireless channels equipped with a novel approach of interference
suppression for which Canadian and international patent applications have
been filed. This new technology currently exists under a software format.
In the mid-term, my research program will validate this technology by rendering
a prototype operational in real-time and on-air, thanks to the equipments
of the High-Speed Wireless Communications Laboratory funded by the CFI in the framework of a
joint
CFI/Canada Research Chairs program. In the long-term, my research team
will devote its efforts to the evolution of this technology towards the
fourth-generation high-speed wireless systems. My research work will focus
on the efficient exploitation of multiple antennas at both the transmitter
and the receiver and their optimal combination with original interference
suppression techniques.
