Abstract:
A method for correcting digital code words in a digital communications network,with digital code words being transmitted via the digital communications network, and with a specific bit in a corresponding code word being changed for an RBS channel in the digital communications network, with training code words transmitted during a training phase being evaluated, in that the presence of an RBS channel is deduced as a function of the result of the evaluation of the training code words, and in that, after identifying an RBS channel, the code word corresponding to the identified RBS channel is corrected by setting the specific bit in this code word to a fixed value, â€ƒwherein the training code words are transmitted repeatedly during the training phase, corresponding training code words which are transmitted during different repetitions via the digital communications network are compared with one another, and if any difference is found between the specific bits in the training code words compared in this way, the corresponding channel is identified as an RBS channel, a specific number of training code words are stored at regular intervals in the form of corresponding data records, and in that the corresponding training code words in the stored data records are compared with one another in order to identify an RBS channel, at least three data records are stored, and the respectively corresponding training code words in the individual data records are compared with one another, with that training code word whose specific bit differs from the specific bits in the other training code words compared in this way being identified as being associated with an RBS channel.
