It is researched active and passive microwave devices, like antennas, filters and amplifiers, built with waveguides, planar lines and radio frequency transistors. There is emphasis in simulation techniques and numerical modeling and in the application of this devices in wireless communication systems. Problems with scattered fields, RCS, radar techniques and interference are also investigated.
This line of research includes the following themes: Performance analysis of communication systems including the efficient use of communication channels, highlighting the use of digital modulation techniques, data compression algorithms, error control and data communication protocols. It is studied Service Quality (SQ) and Experience Quality in network package through modeling and traffic characterization of multimedia data through these networks. Voice and video transportation in network package and communication in multihomed systems are also addressed themes. It includes new advances in wireless communication networks as cognitive radio systems and cooperative communication. It is also approached communication technologies for smart grids.
