[0042] The basic idea of the present invention is: according to the updated LTE protocol, in the conventional CP type and the extended CP type, the PSS timing position and the SSS position have a large timing deviation. After obtaining the PSS timing position and sector ID, the present invention According to the two CP types, extract the sequence of the SSS location in the received sequence according to the PSS timing position, and perform blind detection on the local SSS to obtain two correlation sets. The CP type corresponding to the correlation set where the correlation peak is located is the CP actually used in the cell Types of.
[0043] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments, such as image 3 As shown, the method includes:
[0044] Step 301: Obtain the PSS timing position and sector ID of the received sequence.
[0045] In the LTE protocol, each cell defines three PSSs, which correspond to t...
