Abstract:
1. A method for error handling in transmission of a datum over a communications system, comprising: generating at least two data words consisting of bits for the datum in accordance with a predefined coding rule; selecting one of the at least two generated data words taking into consideration a running digital sum formed over the corresponding data word, wherein the running digital sum of the selected data word is used for formation of a first running digital sum; converting the selected data word by a modulation method into a code data word, wherein each bit of the selected data word is assigned a two-bit string with two different single-bit values; transmitting the code data word and the first running digital sum; analyzing the received code data word to ascertain an error, wherein an error is determined if a two-bit string with two identical single-bit values occurs in the received code data word; and if an error is determined, correcting the error using at least the first running digital sum.
