<p>The invention provides a method of fast cell search for mobile terminal and the apparatus therefor. The mobile terminal first performs coarse time synchronization on an initial synchronization sequence in a received signal, e.g. the downlink synchronization sequence (SYNC_DL) in TD-SCDMA system, to obtain a coarse time parameter of SYNC_DL. Next, It performs correlation calculations between signal sequences possibly conforming to the SYNC_DL in adjacent subframes based on the coarse time parameter, and determines an accurate time parameter of the SYNC_DL from a peak value of the results of correlation calculations. In the end, The mobile terminal determines the SYNC_DL sequence in the signal received by the mobile terminal based on the accurate time parameter, thus achieving the SYNC_DL synchronization and completing cell search.</p> |
