Patent ID: 8867636

Claim:
A method of synchronization in a communication system, the method comprising: receiving and processing, by a receiver, a signal with a centrally symmetric part s(k) exploitable for synchronization, wherein the signal is based on a sequence c(l) exploitable for information transmission from a transmitter to the receiver, the centrally symmetric part s(k) is centrally symmetric in a shape of absolute value thereof, the centrally symmetric part s(k) is of arbitrary length N, the sequence c(l) is a Zadoff-Chu sequence defined as c(l)=W L rl(l+1)/2 , l=0, 1, . . . , L−1, L is odd, where W L =exp(−j2π/L), j=√{square root over (−1)}, and the sequence c(l) is mapped to a cell identification number.
