Project

Project Goal

The project will develop a cognitive impulse radio ultra wideband (IR-UWB) wireless communication system mainly for industrial automation applications. Such scenarios usually require communication to be highly reliable, have very short latency and adjust its parameters to fastly changing radio environments. The latter is caused by other wireless systems operating in the vicinity. IR-UWB can overcome coexistence problem with other standards thanks to its huge bandwidth exceeding 500 MHz and the resulting processing gain and very small emission level which has the lowest disturbing potential.

The cognitive IR-UWB will be characterised by the followings:

  • Continuous observation of the frequency spectrum in the range 3.1- 10.6 GHz allocated to IR-UWB in three dimensions time, frequency and space
  • It will possess certain cognitive capabilities for predicting, for instance the occupancies of IR-UWB channels learning from their manner being seized. Prepare free channels for every user or nodes.
  • UWB communication pairs would access the free channel list through a signalling system

State of the Art

M-2-M-Communication

  • Prozessautomation: Latenzzeiten 10 - 100 ms (drahtgebunden)
  • Fabrikautomatisierung: Latenzzeiten 10 - 100 ms (Feldbus)
  • Sensor-Aktor-Kommunikation: die Latenzzeiten dürfen nur wenige Mikrosekunden betragen; bislang nur drahtgebundene Lösungen (z.B. IO-Link)

Spectrum Scanning and Sensing for cognitive IR-UWB

  • Coherent reception with symbol detection
  • Non coherent reception (energy detection)
  • Non coherent reception with feature detection

Exploitation

KUSZ project will design and implement IR-UWB radio system which can be applied for industrial environment. There is no experience to date in using IR-UWB for industries both as wireless communication and cognitive radio. The combination of these two highly innovative approaches has huge potential to find applications in the future and today this can be overlooked. However, the consortia is fully convinced that the KUSZ project will make valuable contributions to construct the most reliable and robust wireless system for applications requiring high degree of security.
