Synchronization and cell search method and apparatus for wireless communications

A on the related communication signal and public synchronization code for receiving, generating synchronous signal detection. Elimination from the synchronous signal detection with a known synchronous signal and synchronous signal detection device, so that the number of generating a synchronous signal detection of interference gap. A synchronous signal detection and synchronous signal of interference gap timing. To one surface, interference gap and a known and synchronous signal and public synchronization code of estimate correlative value, removing estimate from the synchronous detection signal receiving known synchronous signal and public synchronization code correlative value generating, a synchronous signal detection of interference gap, and achieves. Synchronous signal timing and a synchronous signal detection in a time-gap and detection of accumulation interference gap in aggregated interference gap peak the synchronous signal detection, and a detection peak and synchronous signal timing, which is determined. The other surface, interference gap is under the synchronous signal detection in a time-gap, peak of a known synchronous signal with nothing is made of comprises a synchronous signal detection of accumulation, an, and a detection peak and synchronous signal timing, and achieves. Further discussed related terminal device.
