ABSTRACT:
A reception step receives a multicarrier signal containing subcarriers, at least one of which a synchronization signal is transmitted therein, multiplied only by a synchronization signal spreading code, a correlation detection step detects correlation values between the received multicarrier signal and replicas of the synchronization signal, and a timing detection step detects a FFT timing and a long code received timing according to the correlation values.
