A method is provided for synchronization in a communication system. A receiver receives and processes a signal with a centrally symmetric part s(k) exploitable for synchronization. The signal is based on a uniquely identifiable sequence c(l) from a set of sequences exploitable for information transmission. The centrally symmetric part s(k) is centrally symmetric in the shape of absolute value thereof. The centrally symmetric part s(k) is of arbitrary length N, and the sequence c(l) is a Zadoff-Chu sequence.
