Abstract
Disclosed are example embodiments of cell detection in a mobile communications network. An example method includes performing a detection procedure in the mobile communications network, the detection procedure including correlating two M-sequences to generate two correlations, and combining the two correlations, each correlation expressed as a likelihood of a cyclic shift, combining the two correlations to form a likelihood of a SSS sequence; and performing a signature-based filtering to eliminate a cell detection false alarm peak, the signature-based filtering including comparing a known signature of a specific secondary synchronization signal SSS sequence going through the detection procedure.
