Abstract
A connection (link setup) between individual stations of a radio network may be carried out fully automatically, and even with poor transmission quality, only the wanted stations are activated. A call signal includes a synchronization signal having narrow band, mark and space signals which form the component signals of a diverse pair of signals. A synchronization signal receiver independently detects and evaluates both of the component signals of the diverse pair as well as comparing the results thereof, with means of digital signal processing.
