A method of a mobile radio system for synchronization a transmitter and receiver. The system relates to MC/DS-CDMA-system. In the system information is transmitted digitally in frames. For that 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 .DELTA.. 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 indicates 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 the synchronization channel appoints the position of the data channel.

[ What is claimed is:] [1.] A method for synchronizing a transmitter and a receiver in mobile radio systems, comprising steps of:creating a data channel configured to convey data in a digital format from the transmitter to the receiver, includingdividing the data into frames,grouping the frames into data blocks, each of the data blocks having a predetermined length, andinserting a guard space after each of the data blocks;creating another channel with other blocks, each of the other blocks having a predetermined displacement in position with respect to each of the data blocks, the other blocks being arranged in direct sequence after each other, without guard spaces therebetween; andidentifying the predetermined displacement in position of the other blocks with respect to the data blocks so as to synchronize the receiver with the transmitter.
