Telecommunications for the Digital Transformation Strategic Research Group uri icon

The group works on signal processing for image processing as well as on the convergence between optical communications networks and wireless networks. The group also does research in the following areas: radio over fiber, photonic crystals, levels of physical layer, connectivity, modulation, configurable network architecture and sensors, optimization of optical and wireless networks and several applications such as medical, automotive and biological imaging, among others. Signal processing spans many applications such as images, video, audio, speech, communication codes, biological systems, geological systems, electric power systems, radar, sonar, automotive, signal integrity in RF, RF filtering, smart antennas, fractal signals, nonlinear systems, optical systems and quantum signal processing, among others. One of our research areas focuses on the understanding and development of mathematical algorithms for potential applications and the efficient implementation of such algorithms in DSP processors, specific software or architecture. It is also evident that telecommunications are developing almost exponentially worldwide in response to the ever-increasing bandwidth demand and transmission distances required in communication networks. The systems fit to cope with this exponential growth are led by optical networks. This group does research in long haul transmission systems, advance optical modulation formats, radio over fiber, convergence of networks, photonic crystals, network security and evolutionary algorithms applied to network optimization and design, evaluation of the performance of all-photonic networks and the application of new technologies as quantum security. The Wireless Communications group currently conducts research to improve essential understanding of the fundamental performance in the areas of wireless communications and networks such as 4G, 5G, cognitive radio, position location techniques, interference engineering and modeling, optimum receivers, ad-hoc and sensor networks, vehicular communications (V2V and V2I modeling), network coding, MIMO/massive MIMO, channel modeling, coexistence/collaboration/cooperation in wireless networks, CDMA, multiple access, among others.
