Patent ID: 7940743

Claim:
A method for synchronization of a transmitter station (SE;SE/EE) and a receiver station (EE;SE/EE) which communicate with each other over an interface (V), the method comprising the steps of: in the transmitter station (SE;SE/EE), generating a transmitter signal (sig 1 ) with a signal source (SGEN 1 ) and transmitting the transmitter signal over the interface (V), the transmitter signal (sig 1 ) having a first frequency modulation form; in the receiver station (EE;SE/EE), receiving a receiver signal (esig 1 ) corresponding to the transmitted transmitter signal (esig 1 ) on the interface (V) for evaluating the receiver signal using a receiver signal source signal (sig 2 ) from a receiver-side signal source (SGEN 2 ) matched to the transmitter-side signal source (SGEN 1 ), the receiver signal source signal (sig 2 ) being triggered by a clock of a clock unit (CLK 2 ) of the receiver station, the receiver signal source signal (sig 2 ) and the transmitter signal (sig 1 ) being of the same first frequency modulation form; mixing the receiver signal (esig 1 ) received in the receiver station with the receiver signal source signal (sig 2 ) to form a mixed signal (sigmix); analyzing the mixed signal (sigmix) to determine an adjustment to the clock of the clock unit of the receiver station, the determination based on an analysis of the mixed signal; and adjusting the clock of the clock unit of the receiver station to synchronize the receiver signal source signal (sig 2 ) with the receiver signal (esig 1 ).
