Abstract
A data transmission system for providing error protection of transmitted data words. The less significant bits of a data word are, by means of matrix multiplication, encoded into a first redundant proto-code word and the more significant bits are, by means of further matrix multiplication and delay by different word recurrence intervals encoded in a set of further redundant proto-code words. A composite of the proto-code word is formed by means of a modulo-2-addition of code words, so that for the less significant data bits a block code is realized, while for the more significant data bits a convolutional encoding is realized. In the decoding, the more significant bits of the composite code word are decoded by means of Viterbi decoding, the Viterbi metric being determined from the deviation between the reconstructed contribution of the less significant bits to such code word and the actually received contribution of such bits to such code word.
