Abstract:
A process for the transfer of information comprising:generating at least one information signal (IS) which includes at least one reference component (BK) and at least one information component (I1; I2; . . . ; IN), causing at least one of the components to have a temporally continuous frequency change during the transfer, forming discrete states of the reference component (BK) and the information component (I1; I2; . . . ; IN) for the provision of a bit pattern, and transferring said at least one component with frequency change into constant intermediate frequencies, selecting the best suited signal components from the spectrum of the constant intermediate frequencies separating the best suited signal components as constant frequencies from interference portions, evaluating the best suited signal components with regard to the relevant information parameters, and processing the information signal after reception, by separating the reference component (BK) from the at least one information component (I1: I2; . . . ; IN), wherein the reference component BK is transferred into a transformed reference component BKâ€² and the at least one information component I1; I2; . . . ; IN is transferred into a transformed information component I1â€²; I2â€²; . . . ; INâ€²; and the signal parameters relevant for the information encoding are determined on the basis of the projection of I1â€²; I2â€²; . . . ; INâ€² onto the sine and cosine components of the BKâ€² in each case.
