<p>The present invention relates to a method at mobile radio system for synchronization of transmitter and receiver. The system relates to MC/DS-CDMA-system. In the system information is transmitted digitally in frames. For the purpose a data channel, a pilot channel and a synchronization channel are created. In the data channel the data blocks (D0, D1, D2, etc.) are separated by a guard space Δ. In the pilot channel, respective the synchronization channel, the information is arranged in blocks which are synchronous with each other. The repeating distance, (A), of the pilot channel, corresponds to the length of one of the data blocks (D0, D1, D2, etc.). The repeating distance for the synchronization channel is S, corresponding to a number of blocks in the data channel. In the synchronization channel information is introduced into the blocks which indicate their relation to the data channel. The method in this way allows an identification of the position of the pilot channel, which indicates the position of the synchronization channel, at which a decoding of the information of the synchronization channel appoints the position of the data channel.</p> |
