SECONDARY SYNCHRONIZATION SIGNAL (SSS) POST-PROCESSING TO ELIMINATE SHORT CODE COLLISION INDUCED FALSE CELLS

WIPO Patent Application WO/2014/040069

A3

The invention relates to a method and a corresponding apparatus for detecting a secondary synchronization signal (SSS) transmitted from a base station, comprising obtaining samples of a received signal across one or more reference pilot intervals;processing the samples to detect a plurality of SSS candidates, each SSS candidate having a corresponding first short code and second short code and the processing comprising computing a combined energy metric for each SSS candidate based on the first and second short codes; computing, for each SSS candidate, a first energy metric for the first short code and a second energy metric for the second short code; and selecting one of the SSS candidates based on evaluation of the corresponding first and second energy metrics, wherein the selecting comprises identifying SSS candidates that share a first short code or second short code with another SSS candidate and eliminating identified SSS candidates based on evaluation of the corresponding first and second energy metrics.
