Method and device for detecting primary synchronization signal

A device for detecting a primary synchronization signal, comprising:

• a capturing and storage module, configured to capture a time-domain signal sequence for synchronization;
• a correlation module, coupled to the capturing and storage module, configured to obtain a correlation result corresponding to the time-domain signal sequence, wherein the correlation result is a value obtained from performing a sliding correlation on the time-domain signal sequence;
• a normalization module, coupled to the correlation module, configured to normalize the correlation result according to a received signal strength indicator corresponding to the time-domain signals to obtain a ratio of the correlation result to the received signal strength indicator;
• and
• a sorting module, coupled to the normalization module, configured to sort the normalized correlation result to ascertain a position of a peak value corresponding to the correlation result, wherein the position of the peak value is a position of the primary synchronization signal.
