ABSTRACT:
The invention relates to a method for associating an information unit from a limited set of various/different information units with a signal sector of given length of a data signal transmitted in a signal transmission system and including superimposed disturbances. The transmission of data takes place by a time-succession of the information units in the data signal. The various information units are coded in each case by a typical curve of the data signal in the corresponding signal sector. On the receiver side of the signal transmission system, different partial areas are determined for each signal sector under the curve of the received data signal. The various partial areas are assigned to rating numbers in accordance with their size. Based on the rating numbers, the decision is made as to which information unit has been transmitted in the relevant signal sector.
