Redundant Signal Transmission
First Claim
1. A method for transmitting a digital signal sequence consisting of a prescribed number of individual signals, comprising the following steps:
- repeated transmission of a digital signal sequence consisting of a prescribed number of consecutive individual signals, where the time interval between two consecutively-transmitted digital signal sequences is constant,receiving a first series of consecutive individual signals from the repeatedly-transmitted digital signal sequence, wherein the number of individual signals in the first series which is received corresponds to the number of consecutive individual signals prescribed for the digital signal sequence,determination of a first series of symbol values representative of the first series received, where each symbol value in this first series of symbol values represents exactly one individual signal from the first series which has been received,storing the series of symbol values which represents the first series received in a first register storage device in such a way that each symbol value from the series of symbol values is stored in a separate storage area in the first register storage device,receiving at least one further series of consecutive individual signals from the repeatedly-transmitted digital signal sequences at a defined time interval after the preceding series of consecutive individual signals which was received, where the number of individual signals in the further series which has been received corresponds in turn to the number of consecutive individual signals prescribed for the digital signal sequence,determining a further series of symbol values, representing the further series which has been received, where each symbol value in the further series of symbol values represents exactly one individual signal in the further series which has been received,carrying out a mathematical operation with the first series of symbol values and the further series of symbol values as the arguments, where this mathematical operation is applied in each case to symbol values which correspond to each other in the two series of symbol values and a symbol value from the first series of symbol values then corresponds to exactly one symbol value in the further series of symbol values if and only if both have the same position in their respective series of symbol values, andstoring the result of the mathematical operation in the first register storage device.

Abstract
In a method and a device (10) for transmitting a digital signal sequence, with a prescribed number of individual signals, over large distances relative to the transmission power, the digital signal sequence is repeatedly sent from a first communication device (1, 1a). A second communication device (2, 2a) receives the repeatedly sent signal sequence, wherein a first series of consecutive individual signals of the repeatedly sent digital signal sequence is received (S1) first, the number of individual signals corresponding to the number of consecutive individual signals prescribed for the digital signal sequence. The sequence of individual signals is converted into a sequence of symbol values representing the individual signals and stored in a register (24). Further sequences of individual signals received at a defined time interval after the first sequence of individual signals are also converted into symbol value sequences and superimposed on the sequence stored in the register (24).
