Abstract: A method is described for detecting the time messages in the faulty signal of a time-signal transmitter comprising the steps below. Probabilities are assigned to the received information/bits as they are received and whose sign specifies the value of the bit and whose numerical value indicates the certainty of reception. Except for the bits designating the minute information, the probabilities of successive time messages are totaled with time correctness in a one-dimensional memory field. From the totaled probabilities, a reduced time message is reconstructed that initially contains no information on the minutes. If the reconstructed time message does not change over two successive time intervals, and if preset minimum values for the number of probabilities are exceeded for all bits, then the reduced time message is recognized as being correct. The minutes are determined separately and added to the time message recognized as being correct.

Abstract: The invention relates to a method for detecting the beginning of time messages in the signal received from a time-signal transmitter. The signal of the time-signal transmitter consists of a series of blanking intervals on a carrier signal in the seconds clock cycle in which blanking intervals of different length cause different information units to be transmitted (ZERO pulse, ONE pulse, frame pulse). A time message, comprising the information units transmitted over a period of one minute, contains the actual time information in coded form. The time message has areas/sectors with defined, constant information units and areas/sectors with variable contents that code the time information. A reference message is stored in a first area of memory that contains the defined, constant information units that are located in fixed areas/sectors. A number of successive information units corresponding to the length of a time message are stored in a second area of memory.

Abstract: The invention relates to a method for decoding transmitted information units by comparing a signal section containing an information unit with a number of reference functions. A reference function is assigned to every possible information unit and that type of information unit is considered to be recognized for which the smallest deviation is established between assigned reference function and signal section. In the method according to the invention, the reference functions are modified in accordance with the signal curve in the respective actual signal section. The modifications are appropriately calculated using a fuzzy controller.

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.
