Summary:A synchronization signal detection apparatus includes a temporary synchronization signal detector and a final synchronization signal detector. A header of a synchronization signal has at least M successive bits of a first level, where M is an integer more than the Nth power of 2, and N is a positive integer. The synchronization signal has alternating bits starting with a second level. The temporary synchronization signal detector detects the Nth power of 2 successive bits of the first level as a temporary synchronization signal when receiving the Nth power of 2 successive bits of the first level before receiving the alternating bits. The final synchronization signal detector determines that the detected temporary synchronization signal is the header when receiving the at least M successive bits of the first level.
