Weekly Seminar: “Broadband Satellite Communications: State of the Art and Future Evolutions”

Speaker: Alberto Ginesi, Head of the Communication-TT&C Systems & Techniques Section ESA

ABSTRACT:  The presentation will address the state of the art and future evolutions of satellite broadband networks from the system and physical layer access point of view. After a short introduction of satellite broadband communication networks as well as a review of existing or planned high throughput satellites, the key evolutions at system/physical layer will [...]

Weekly Seminar: “Manufacturing goes digital”

Speaker: Helena Martínez, Xavier Sol

ABSTRACT: As digital tools are gaining ground in business management, traditional sectors such as manufacturing also turn into digital. It can not be otherwise: task automation, telecommunications networks, sensing and signal transmition, remote machines, augmented reality … these technologies take already a significant role in the production processes. The question is why not including the [...]

Weekly Seminar: “GEODA antenna system for satellite communications”

ABSTRACT:  With the fast growth in the number of satellites in the last decade , particularly in the LEO (Low Earth Orbit) and MEO (Medium Earth Orbit) constellations, it is necessary to work with ground stations that allow monitoring and control the satellites (TTC operations). The current solution based on satellite dishes can not cover [...]

Weekly Seminar: “Laser Safety in Optical Fiber Communication Systems”

Place: CTTC Auditorium, October 23rd, 10:00h

ABSTRACT: In Optical Fiber Communication Systems the optical radiation is completely enclosed under normal operation and hence no optical energy is accessible to the operator or any other personnel. However, a risk of exposure to optical energy above the safe limits may arise during service operations or in the event of a fiber breakage. IEC [...]

Weekly Seminar: “Design of the Interconnect for Effective Chip Multiprocessor Systems”

ABSTRACT: Current technology still pushes for higher number of nodes in future chips. Chip Multiprocessor systems (CMPs) and Multiprocessor System-on-Chip (MPSoC) systems are targeted with the many-core approach where tens and hundreds of cores are expected to be supported. In such configurations, the network inside the chip plays a central role, shifting the system from [...]

Weekly Seminar: “Wireless Sensors as a Window into the Autonomic Nervous System”

ABSTRACT: Wireless sensors can measure important physiological signals without interfering with everyday life. Among these signals, the heart beat-to-beat intervals time series is easily measurable and can reveal valuable information about health and disease conditions. It is informative on both the state of a single individual and surprisingly also on the dynamics of a group [...]

Weekly Seminar: “Equalization and Adaptation of Nonlinear Systems”

ABSTRACT: This talk provides a tutorial introduction to nonlinear signal processing with emphasis on equalization of nonlinear distortions in practical problems and adaptation of nonlinear system models. In the first part of the talk, we will discuss efficient approaches to inversion and equalization of a broad class of nonlinear systems. We will start by looking [...]

Weekly Seminar: “Compressive Sensing for Urban Radar”

ABSTRACT:  Towards the objective of providing timely actionable intelligence in urban environments, compressive sensing (CS) and sparse reconstruction techniques have recently been shown to yield reduced cost, simplified hardware, and efficient sensing operations that allow high-resolution imaging of sparse behind- the-wall scenes. Compressive Sensing for Urban Radars, or Compressive Urban Sensing, is an area of [...]

Weekly Seminar: “Robust and scalable sensing for tomorrow’s power grids”

ABSTRACT: The smart grid vision urges for enhanced situational awareness over our power systems. While sensing and data networks are being installed throughout the grid, algorithms that can efficiently process the “big data” deluge of possibly unreliable meters are now demanded. This talk first focuses on robust sensing, defined as the task of recovering information [...]

Weekly Seminar: “Towards Greener Smartphones with Microwave Measurements”

ABSTRACT: Today’s smartphone handsets offer a wide range of functions (phone, GPS, Bluetooth, WiFi, .) to customers, although are still perceived as expensive and energy consuming (requiring a daily recharge). The aim of this talk is to show how microwave measurements impact smartphone design. By optimally engineering the type of measurements made before and after [...]
