Method and system for improving forward error correction in serial coding during data transmission

A system arrangement for improving the forward error correction in serial line

• coding in a data transmission in the vehicle, comprising an interface unit set up to provide (100) user data to be transmitted;
• a splitting unit set up for splitting (101) the user data provided into a plurality of bit sequences of the same length in each case;
• a further interface unit set up for reading (102) a subdivision rule from a hardware architecture, wherein the subdivision rule is not stored in a data memory, which subdivides a bit sequence into a sequence of segments each of predefined length at a predefined bit position, in such a way that different encoders are provided for different bit lengths and the corresponding segments correspond to the respective encoders;
• a subdivision unit arranged to apply (103) the read-out subdivision rule to all bit sequences of the plurality of bit sequences;
• a correction unit arranged to generate (104) in each case information for partial forward error correction for all segments of the same bit position over all bit sequences;
• an encoder unit set up for (105) applying a segment encoder in each case over all segments of the same bit position for generating segment line codes over all segments per bit position and per bit sequence;
• a further coding unit arranged to apply (106) to the respective partial forward error correction the respective segment coder which was also applied (105) to the segments with respect to which the respective partial forward error correction was created (104) in order to generate a respective partial forward error correction guide code for each partial forward error correction;
• and
• a transmission unit adapted to transmit (107) all segment line codes and all partial forward error correction line codes.
