Abstract
Depending on the sequence of the decoded payload signal bits (a, . . . , a) and redundancy checking bits (p, . . . , p) which are produced by the Viterbi traceback, either some of these bits are inserted by means of a distribution device () from the front into a linear feedback shift register (), or some of these bits are inserted by means of the distribution device () from the rear into a linear feedback shift register (), or all of them are inserted into a linear feedback shift register () from the rear with the allocated coefficients being unchanged, or all of them are inserted into a shift register from the front with the allocated coefficients being inverted. This allows a redundancy checking process to be carried out on a transmitted data block in the shift register () without temporary storage of the bits produced by the decoding process.
