ABSTRACT:
A device for multi-channel signal transmission between mobile units, including at least one first transmitter/unit that is coupled to at least one second transmitter/receiver unit via transmitting means. Further more the first transmitter/receiver unit and the second transmitter/receiver unit provide mutually tuned filter banks that filter predetermined characteristic spectral fractions out of the signal to be transmitted and which combine these signals to form a cumulative signal in the cast of transmission, that pass on these signals via directional switches which separate the signals of the transmission and reception path from each other or combine transmitted and received signals in such a way that they will be transmitted via common transmitting means.
