ABSTRACT:
A synchronization signal used to synchronize base stations in a mobile radio telecommunication system having a first sequence followed by a second sequence, the first and second sequences being polyphase complementary sequences configured such that when the synchronization signal is correlated with a replica of the first sequence and a replica of the second sequence, and the correlation results are added, exemplary synchronization results are obtained.
