摘要
A data block protection information code word (BSI) is formed by division of a message polymonial representing a data bit sequence (D) by a generator polynomial representing a cyclical binary code. Registers are arranged in register chains in a coder unit provided for this purpose with a polynomial ordinal number being allocated to every register representing a member of the binary code. Given the presence of a term at the ordinal corresponding to the registers (R) of the respective register chains (RK) missing in the polynomial ordinal seris, a respective logic element (V) is inserted to which an operation information is supplied, said operation information being formed in a means for the formation of the operation information (EBV) by parallel processing of a plurality of data bits together with information at the outputs of the registers (R) corresponding to the highest polynomial ordinals. As a result thereof, the processing speed of a coder unit is reduced, and thus, making possible the use of programmable or computer-controlled coder units with high speed data transmission rates.
