OPERA WCG

Wireless Communications Group

Founded in 2007, the Group owns expertise in twoo complementary fields:

propagation channel modeling (Pr. Philippe

     De Doncker)

digital signal processing (Pr. François Horlin)

Propagation channel modeling

The mission of the channel team is the theoretical and experimental characterization and modeling of propagation for emerging communications systems. Expertise range from propagation in indoor environments, urban, and in the near-body region, from HF to mm-wave frequencies.

Digital signal processing

The mission of the DSP team is to develop solutions for emerging digital communications, localization and passive radar systems taking into account hardware implementation and integration constraints. The team studies modulation, access techniques, channel equalization and synchronization.
