XG - Next Generation Sensing and Communication
Contact: Leo de Vreede
MotivationThe human desire for "smart environments" and "to be connected anywhere, anytime" is changing the way we interact with our surroundings and will drastically impact our society. Wireless data traffic is growing exponentially and is driving mobile networks and their devices from 4G+ to 5G services, to handle more users and services at higher data rates and lower latency. Consequently, the use of larger signal bandwidths and massive MIMO techniques will be mandatory. At the same time, the Internet-of-Things evolution will require connectivity of large numbers of devices at low data rates, but with very strict requirements on response times and energy usage. Spectrum scarcity will demand dynamic spectrum usage based on cooperative spectrum sensing and cognitive radio concepts. Moreover, GPS-free, reliable and accurate location estimation will prove to be an essential feature. While in the enhancement of societal safety and security (including environment monitoring and autonomous transportation), microwave and THz sensing systems are expected to play a crucial role.
XG ThemeThe XG theme is a faculty-wide initiative combining expertise on electronics with that of networks and embedded systems. Within the theme, a number of societal applications are addressed:
- Autonomous driving - distributed sensing and high accuracy localization
- Wireless communication - 5G and beyond
- THz sensing
TechnologyWireless sensing and communication systems share the need to transmit and receive EM waves. This yields, in spite of their different signal processing, to similar requirements on system architecture and hardware technology. To serve both in a cost-effective and ecologically responsible manner, while benefiting directly from Moore’s law, novel reconfigurable highly integrated TX/RX solutions with multifunctional antenna systems and embedded signal processing capabilities are envisioned to be implemented in advanced semiconductor technologies. Cognitive/automated usage of EM spectrum, adaptive hardware and signal processing, cognitive sensing and network management are expected features of these next generation wireless systems.
ChallengesScientific challenges are found in identifying and implementing new technology, design and system concepts that are truly energy-efficient, modular, data-rate scalable, frequency agile and cost-effective, while providing high functionality and data quality under intelligent control. These multidisciplinary challenges provide increased focus and synergy among the research groups within EEMCS that want to be leading in these developments and aim to provide the wireless communication and sensing solutions of the future.
DisciplinesCovered disciplines are electronics, digital, RF, (sub)mm-wave and THz circuit design, signal processing, cognitive/automated networking, embedded systems as well electromagnetics, antennas, remote sensing and space satellites applications.

Slimme sensor die energie uit de lucht plukt, heeft eindeloos veel toepassingsmogelijkheden
Begin oktober gingen ze in het kader van een pilot het asfalt in: slimme sensoren die de temperatuur in het wegdek meten, zodat onder andere veel gerichter en efficiënter tegen gladheid kan worden gestrooid. De innovatie werd mede mogelijk gemaakt door de sectie Bioelectronics binnen de faculteit Elektrotechniek, Wiskunde en Informatica van de TU Delft die zich volgens hoogleraar Wouter Serdijn vooral bezig houdt met…de elektronische behandeling van aandoeningen in het menselijk lichaam.
NWO-High Tech Systems and Materials proposal awarded to ECTM
Sun sensors, which are used to determine the satellite orientation towards the sun, are a vital part of the satellite attitude control. Current commercial available sun sensors are too large and costly to be integrated in the small satellites, e.g., nanosats. Due to the low costs of these satellites, they enable a wide range of applications which otherwise would not be possible or cost-effective. By developing a sun sensor that is fully integrated on a single substrate, the overall size of the sensor can be significantly reduced and costly extra calibration is avoided. By using SiC as material, we secure high performance and high reliability under harsh environment. In addition, the sensor will not be sensitive to reflections of the earth, as it uses the parts of the light spectrum absorbed by the atmosphere.
