Research area and interests

The Advanced Signal Processing Group (GTAS) of the University of Cantabria conducts research in the general area of wireless communication systems with particular emphasis on multiple-input multiple-output (MIMO) transceivers. Using theories and tools from adaptive learning, multivariate statistical analysis and information theory, this research group is investigating various practical problems that arise in multiterminal wireless communication systems and sensor networks.

In the context of the OPTICWISE Cost Action our main interest is to explore the application of multiple-input multiple-output (MIMO) technologies (e.g., orthogonal space-time coding, MIMO beamforming or spatial multiplexing techniques) to optical wireless (free-space) communications. Adverse atmospheric conditions, such as turbulence, or effects like scintillation, make that optical wireless channels and their fading behavior are drastically different than those typically encountered in radio frequency bands, this poses new research challenges of interest to our group. As another example of interest to our group we would be interested in the development of beamforming techniques in the optical domain. In these topics, we would be interested in establishing research and project-oriented collaborations with groups with expertise in photonics and optics.

Research Facilities


· The GTAS group has equipment for simulation, prototyping and testing of MIMO wireless communication systems. More specifically, we have developed a multiuser MIMO platform composed of 3 MIMO nodes with 4 antennas each one (shown in the figure in next page). The MIMO nodes are equipped with a Quad Dual-Band front-end from Lyrtech. This RF front-end is based on MAX2829 chip. It supports both up and down conversion operations from either a 2.4 to 2.4 GHz band or a 4.9 to 5.875 GHz band. Each node is also equipped with a VHS-DAC module and a VHS-ADC module respectively containing eight DAC and eight ADC. Each pair of DAC/ADC is connected to a single transceiver of the RF front-end, and the signals are passed in I/Q format. This multiuser MIMO testbed has been already used for the practical evaluation of multiuser MIMO technologies such as interference alignment.


· The group also has several FPGA/DSP development tools for the implementation of real-time signal processing algorithms.
