Associate Professor
PhD in Telecommunication engineer

Education

2009 Marie Curie International Outgoing Fellowship (EU People Program 2008).
University of Vigo – New Mexico State University.
Research topics: Adaptive noise UWB radar for propagation through dispersive media applications.

2006 Ph. D. Electrical Engineering.
Universidade de Vigo.
E.T.S.E. de Telecomunicación, Vigo, Spain.

Ph. D: Thesis: Characterization and Modelling of the Radio Channel for Broadband Multimedia Systems at 40GHz.
Research Advisor: Manuel García Sánchez, Professor at University of Vigo, Spain.
Dissertation Topic:
Along the PhD Thesis, a complete study was performed about the characteristics of the radio channel at 40GHz. In this research work all the main propagation effects that can affect the correct performance of a Multimedia Wireless System (MWS) link, which frequency band covers from 40.5 to 43.5GHz, were included.

The great objective of the PhD Thesis has been the wideband sounding of radio channel in the 40GHz band. In order to cover this point, a measurement system was developed based in the STDCC scheme, but introducing changes to the classical configuration to improve the performance of this kind of sounders. Millimetre wave propagation have been studied both in outdoor and indoor conditions.

The characterization of site shielding became another great objective of the PhD Thesis. All propagation mechanisms have been characterized: transmission through, diffraction over and around, and reflection from obstacles, but also attenuation though vegetation.

There are not many references related to any of these characterizations in the 40GHz band. So, the results achieved are of great interest.
