For a transmission signal for a wireless communication system and a method and apparatus for performing synchronization processing for the transmission signal provided by the present invention, the principal ideas is that, a synchronization sequence is respectively inserted into a group of transmission datum according to predetermined time offsets to form a group of transmission signals. The synchronization sequences inserted into the transmission datum are obtained respectively by performing a phase modulation for the same known basic synchronization sequence according to the predetermined phase offsets, dispersed in the same transmission signal period without overlapping with each other, and transmitted by different transmit antennas. By using the transmission signals and the structure of their synchronization sequences, the receiver side only needs to search a part of the received signals, then one of an expected group of synchronization sequences, served as the main synchronization sequence, can be acquired quickly, and based on this, the synchronization positions of the transmission signals from other transmit antennas can be estimated, at the same time, by using the phase offsets between the synchronization sequences and the basic synchronization sequence, the transmission signals from different transmit antennas can be distinguished effectively. |
