This paper describes a monolithic integrated transceiver chipset intended for impulse radio (IR) Ultra-wide band (UWB) applications including indoor communication and indoor localization. The chipset operates in the higher UWB band centered at 7.68 GHz and it is optimized for a pulse bandwidth of about 1.5 GHz. The average pulse repetition rate of 60 MHz and an octagonal pulse position modulation...
Over decades and under varying names the study of complex, e.g. biology-inspired algorithms concerned with self-organization has been the subject of a small and somewhat exotic research community. Only the recent coincidence of a growing inability to master the design, development and operation of increasingly complex system and processes, and an accelerated trend towards a naive if not romanticizing...
In less than 400 years rationality took us from witch burning to the moon. Current societal developments suggest that it may take much less time to send us back to where we came from. Our languages (natural and scientific) have become vague, blurred, ambiguous and inconsistent; what we say is increasingly no longer what we mean or what corresponds to experience and other kinds of knowledge. Often...
Industrial and logistics processes and scenarios are a major field of increasing use of wireless technology. Particularly the attempt to increase the efficiency of processes requires the stringent supervision of goods, tools and machinery as to their states and position/location. The plurality, heterogeneity and independence of processes in a production environments make their radio control and spectrum...
Until UWB became a widely spread subject of research, wireless telecommunications applications were driven by the need to make highly efficient use of spectrum resources, that existed only in scarce quantities. In order to avoid "chaos" in the few allocated frequency bands, standards relying much on the central management of the available resource were considered the appropriate regulative...
