MIMAX aims at developing of a pervasive, low-power consuming and low-cost MIMO network platform with reliable data-rate of up to 100 Mb/s in environments with strong multipath and coverage ranges up to several hundred meters. The current state-of-the-art performs the combining and processing of the complex antenna signal in the baseband. Since complete transmitter and receiver paths are required for each path, the resulting power consumption and costs of conventional MIMO approaches limit applications for ubiquitous networks.

This coordinated proyect has four partners: Universidad de La Coruña, Escuela Politécnica Superior de Mondragón, Centro de Investigaciones Tecnológicas de Guipúzcoa (CEIT) y Universidad de Cantabria (GTAS). The aim of this project is the development of novel signaling schemes that deliver on the full range of multiplexing, diversity and directivity gains inherent to the MIMO multiterminal networks. The project also considers the assessment of the developed signaling techniques in realistic scenarios.

This is a coordinated project in which four research institutions (Universidad de La Coruña, Universidad de Sevilla, Centro de Investigaciones Tecnológicas de Guipúzcoa (CEIT) y Universidad de Cantabria (GTAS) ) investigate new transmission techniques for signal processing and space-time coding for MIMO channels that will enable us to approximate, as much as possible, to the limits predicted by the information theory.

Arousals frequently appear in subjects with sleep disorders (obstructive sleep apnea, OSA, for instance). Therefore, scoring and detecting arousals is a key point in order to assess the quality of sleep. Typically, this scoring task is manually carried out by an expert, according to his/her expertise. In this coordinated proposal, the GTAS research group collaborated with a group of physicians with a broad experience on sleep disorders. The aim of the project was to develop a software tool for automatic arousal detection and scoring.

The partners of this project were the University of La Coruña, University of Alcalá, University of Sevilla and the University of Cantabria (GTAS). Its goal was the construction of a software radio platform for the development of radio interfaces for the fourth generation of mobile communication systems (4Gmobile). These systems will demand data rates much higher than those provided by current systems.

In collaboration with the RF research group of the University of Cantabria, the goal of this project was to development power linear amplifiers for communication applications working from microwave to millimetre-wave frequency bands. The work was carried out following two different lines on the basis of the techniques to be used as well as of the frequency band of the system. 1) Firstly, new nonlinear model amplifiers as well as new predistorting and linealisation techniques for low microwave frequency bands (L and C) were developed.

In this project we developed hardware components for a WLAN network based on industrial PCs and specifically designed for surveillance and access control systems. A Plug and Play WLAN 802.11 card based on the ISA bus was developed using the architecture provided by Intersil-AMD and known as PRISM. PRISM supports the PHY and MAC layers of the IEEE 802.11a standard.

The basic goal of the MOBILITY project was to provide real-time TV broadcasting services to ships via satellite. A mobile DVB-S receiver was designed and developed. It consisted of three main parts: a high-gain broadband antenna, a pointing antenna mechanism will allow the terminal to track the GEO satellite regardless of the ship movement, and a set of sensors to adquire the information about the ship motion. The project included field trials where the receiver was sucesfully tested in a real maritime scenario. The receiver was installed during 45 days in the Juan J.

The goal of this project was to design and develop ASICs for distributing satellite digital TV signals through collective antenna systems (SMATV) including the receiver for final users. Specifically, the project was focused on the design of the Transparent Digital Transmodulator (TDT), which performs transmodulation of the signal received at the head-end from QPSK to 64-QAM; as well as for the Integrated Receiver Decoder (IRD), which includes blind equalization of the SMATV channel, demodulation and decoding.

This was a coordinated project in which 10 spanish universities were involved. Its goal was to apply techniques such as neural networks, nonlinear dynamical models and genetic/evolutionary algorithms, including their combinations with advanced signal processing methods (based on higher-order statistics, for instance) to a set of selected problems in the areas of medical imaging, bussiness, energy and communications.
