An improved method for conveying data and synchronization information in a telecommunication system is disclosed. The method uses a cyclically permutable code, to which a repetitive structure has been imposed, for carrying the data and synchronization information. The decoding procedure at the receiver then uses this repetitive structure of the code to reduce complexity by first evaluating, by use of hypotheses Hx, the repetitive codeword structure of received codewords and choosing a hypothesis corresponding to the repetitive codeword structure. Then the decoding procedure performs diversity combining of codeword elements of the codewords in accordance with the chosen hypothesis. The received codewords are further detected by comparing the diversity combined codeword elements to all possible codewords fulfilling the hypothesis.
