METHOD AND DEVICE FOR THE SYNCHRONIZATION OF RADIO STATIONS AND A TIME-SYNCHRONOUS RADIO BUS SYSTEM

摘要

The invention relates to a method for the synchronization of a transmitter station (SE) and a receiver station (EE) which communicate with each other by means of a radio interface (V). A transmission signal (sig1) is produced with a signal source (SGEN1) in the transmitter station (SE) and is transmitted via the radio interface (V). A corresponding receiver signal (esig1) is received in the receiver station (EE) from the radio interface (V) and is evaluated using a receiver signal source signal (sig2) from a signal source (SGEN2) of the receiver adapted to the signal source (SGEN1) of the transmitter. In order to improve synchronization and correction of momentary deviations, the same frequency modulation is applied to the receiver signal source signal (sig2), whereby the receiver signal (esig1) received in the receiver station (EE; SE/EE) is mixed with the receiver signal source signal (sig2) to form a mixed signal (sigmix) and the mixed signal (sigmix) is analysed with respect to frequency unbalance.
