Efficiently transmittable bit sequence with restricted disparity, and encoded forward error correction

A system arrangement for use in an automobile for generating an efficiently transferable bit sequence as a total symbol sequence with a restricted disparity and a restricted run length, comprising

• an interface unit arranged to provide (100) user data and subdivisions of user data in a bit sequence of the same length;
• a segmentation unit adapted to segment (101) the provided bit sequences into a predefined sequences of segments according to a respective predefined bit length at a predetermined bit position in accordance with a read-out subdivision rule;
• a calculation unit arranged to calculate (101A) a forward error correction for each of the segments, wherein the forward error correction is calculated (101A) for each of the segments in such a way that segments at the same bit position are grouped together and the forward error correction is formed on this basis;
• an encoding arrangement arranged for line coding (102) each segment of the same bit position together with its/their forward error correction into one or more partial symbols in each case, using in each case the same encoding unit for the segments of the same bit position and the associated forward error correction from a plurality of encoding units, whereby the respective encoding unit used takes into account the predefined bit length, wherein a first subset of encoding units actively controls a sign of the disparity of the subsymbol by inverting the disparity of the generated subsymbol to compensate a disparity of a second subset of encoding units, wherein a concatenation of the subsymbols according to the order of the segmented (101) predefined sequence results in the efficiently transferable bit sequence together with the calculated forward error corrections, wherein the active control of the sign is performed by dividing the generated partial symbol into two data streams and conditionally inverting the partial symbol in each case, wherein a multiplexer selects, when a data stream that is positive with respect to the disparity and a data stream that is negative are present, the data stream that contributes to minimising the total disparity of the overall symbol.
