Abstract
A method for measuring transmission characteristics of a transmission path between a transmitter and a receiver. A first transmitter sends a first signal into a first transmission path. The first signal is detected by the receiver. A second transmitter sends a second signal into a second transmission path having known characteristics or characteristics that can be predetermined. The second signal is superimposed with the first signal. A transmission signal is intermittently distributed between the first and second transmitters in a controlled manner. The signal received by the receiver comprises first and second signal components to be assigned to the first and second transmitters, respectively. The first signal component averaged over a predefined time period essentially is exactly as large as the averaged second signal component and the deviation between the averaged signal components is at least intermittently used as control signal for the switching between the first and second transmitters.
