Patent ID: 8116385

Claim:
A method for transmitting a data word containing a sequence of individual data in sequential data positions, the method comprising: making a code word supply available, a number of individual codes words of the supply corresponding at least to the number of data positions of the data word, a cross-correlation function of each code word with a specific reference having in each case a distinct, detectable extreme value having a position is characteristic of the individual code word; assigning an individual code word of the number of code words to each data position of the data word; combining the assigned code word with the particular datum of the data position so as to form a data position-specific combination result; summing the data position-specific combination results to form a sum word; transmitting the sum word to a receiver; cross-correlating the received sum word with a further reference, the further reference, when cross-correlated with each code word, having in each case a distinct, detectable extreme value having a position being characteristic of the individual code word; and reconstructing from the position and magnitude of the values of the thus formed correlation function, the particular data position-specific data of the data word in that, following the fixed assignment, a corresponding datum is assigned to each value; wherein the sum words are provided with a cyclic extension dimensioned so that, in spite of transmission-induced sum word interferences within a correlation window, only sum word components occur which originate from one single, original sum word.
