Abstract
To improve the recognition of the validity of coded control information that is transmitted, together with associated useful data, as a data signal and that is decoded at the receiver by means of a Viterbi decoder (VDCOD), it is proposed that at least an end section of the received, convolution-coded control information is prefixed to this same information, the length of the end section being at least that of the convolution-coded tail bit-sequence, and the information that has been assembled in this way being fed to the Viterbi decoder to allow the convolution-coded control information to be decoded.
