Abstract
A process and system for the transfer of information, which is suitable in particular for digital information transfer. At least one information signal is created, consisting of at least one reference component and at least one information component, wherein at least one of these components has a temporally continuous frequency change during the transfer and, in addition, the reference component and the information component form discrete states for the provision of bit patterns. After receiving, the at least one component with frequency change is transferred into constant intermediate frequencies. From the spectrum of the constant intermediate frequencies, in each case the best-suited signal components are selected, separated as constant frequencies from interference portions and evaluated with regard to the relevant information parameters. This allows a signal transfer with high quality and high transfer rate, even over great distances, for example, under water. Furthermore, a suitable evaluation system is described.
