Abstract
The present invention discloses a method for joint secondary synchronization signal detection and frame timing synchronization, including: (1) generating local secondary synchronization sequences SSCand SSCaccording to a sector number of a cell group; (2) converting a received time domain signal to a frequency domain signal to obtain secondary synchronization signals Sand Sto be detected; (3) performing inner product operation to obtain P=P−1+[S,SSC]+[S,SSC], and P=P−1+[S,SSC]+[S,SSC]; (4) selecting the maximum value P of absolute values of correlation values in the Pand P, and judging whether the maximum value P is greater than a preset threshold Tmax, (5) if yes, taking the index of the maximum value P as an ID number of the cell group, or else, further carrying out step (2), and then further carrying out step (3).
