(57) The invention relates to a process for recovering transmitted test data in cellular digital streams at the receiving end in which the test data are coded by means of code words which, in selfcorrelation, generate a Dirac pulse and in which a cross-correlation is undertaken on the reception side for decoding. In order to be able to transmit a larger number of test data in coded form, a binary zero word (stored at St=1) is added to the code words on the transmission side and the various test data (e.g. 11101) are allocated to the various code words and the zero word. The sum of the digits of the code words received and the zero word is made in addition to the cross-correlation on the reception side. |
