KOSYS: Koexistenzoptimierte industrielle Funksysteme
Heterogeneous radio systems for industrial applications suffer to a certain degree from coexistence limitations. To avoid these impairments this research project deals with the investigation of coexistence optimized radio systems based on cognitive strategies. Coexistence optimized cognitive radio systems achieve always the best system performance in each environment, i.e. data transmission with best quality-of-service parameters and minimal interference to other radio systems.
A successful implementation of this new strategy enables the following features:
· Existing radio systems - so called primary user - will not be impaired by additional coexistence optimized cognitive radio systems.
· Coexistence optimized cognitive radio systems detect and exploit existing temporal and spectral gaps for their data transmission as secondary user.
· The spectral efficiency in a space area will be improved by additional coexistence optimized cognitive radio systems.
